The Dangers of Getting an Eyeball Tattoo

An eye tattoo is a dangerous cosmetic body modification. Learn about the risks and side effects.

Disclaimer: Due to the high risk of serious complications and the lack of legal safety standards, medical professionals strongly advise against eyeball tattooing. Eye health should be prioritized above any cosmetic or aesthetic preferences.

What is eyeball tattooing?

Getting an eyeball tattoo is a type of extreme cosmetic body modification.

It’s also known as scleral tattooing, and is a highly controversial and risky cosmetic procedure in which ink pigment is injected into the white part of the eye (the sclera).

The purpose of this procedure is to change the color of the eye or create a specific design or pattern on the eye’s surface.

As the tissue of the eye is very different to that of the skin, the process is not like any other tattoo procedure, and it’s extremely dangerous.

It involves injecting tattoo ink (like purple liquid, or any other color) into the thin layer of tissue that covers the sclera using a needle or specialized tattooing equipment.

The injected pigment then spreads within the eye’s tissues, creating the desired effect. The risk is that the ink can spread beyond the injection sites and cause permanent damage.

What is the history of eyeball tattoos?

The history of eyeball tattoos (also known as sclera tattoos) is relatively brief and marked by controversy.

While body modification and tattooing have been practiced for thousands of years, the specific practice of injecting ink into the eyeball for aesthetic and cosmetic reasons has emerged much more recently.

Owing to the severe health risks and potential for vision loss associated with eyeball tattooing, it has been met with widespread disapproval from medical authorities (Hida et al. 2022).

It has also prompted legal restrictions or bans in several countries. Eyeball tattoos are also uncommon because few tattoo artists are comfortable or willing to do them.

DID YOU KNOW?

An eyeball tattoo, or sclera tattoo, is a highly dangerous cosmetic body modification. It is done by injecting ink pigment into the eye’s white part (sclera) to change its color or create a design.

What are the risks and side effects of scleral tattooing?

The eye is a sensitive, delicate organ that must be treated with care. Scleral tattooing is a dangerous and irreversible procedure, with a high likelihood of severe complications and side effects (Rohl et al. 2021).

Additionally, since sclera tattooing falls outside the realm of traditional tattooing, there is currently no established formal training, licensing, or certification process for a tattoo artist to perform this procedure.

Here are some of the many potential health risks of getting an eye tattoo:

Vision issues (blurred vision, decreased vision, or double vision)
Partial vision loss
Blindness
Eye infections
Inflammation of the eye
Retinal detachment
Sensitivity to light
Loss of the entire eye

Even if this high-risk procedure is done without damaging the eye, it still poses challenges for future eye examinations by healthcare professionals in assessing your eye’s health.

Plus, there’s no scientific research on the long-term side effects of sclera tattoos yet, as the first reports of this practice only date back to 2007.

Even the developer of the procedure, body modification expert Luna Cobra, advises against it.

Are eyeball tattoos legal?

Although this is a relatively new procedure, the dangerous nature of eye tattooing has already been recognized (Rohl et al. 2021).

The legality of eyeball tattoos varies from country to country and even within different states or regions.

Some countries and regions have outright banned eyeball tattoos due to the significant health risks associated with the procedure. In other places, it may be allowed but strictly regulated.

For example, in the United States, sclera tattooing is now banned in states like Oklahoma, Indiana, and Washington.

In Australia, eyeball tattooing is prohibited by law unless performed by a medical practitioner or other prescribed persons.

Safer alternatives to eye tattoos

It’s vital to prioritize your health, even if you don’t like the color of your eyes. A safer alternative to getting a sclera tattoo is to use colored contacts (also known as cosmetic contacts or costume contacts).

Colored contact lenses can change the appearance of your eye color without the need for any invasive procedures.

They are available with or without a prescription and can offer a wide range of natural or vivid color options.

Remember that it’s also essential to consult a qualified eye doctor before using any cosmetic eye products or considering non-surgical enhancements.

They can provide guidance on the correct size and brands and ensure that any chosen method is safe for your eyes and vision.

If you have any questions on this matter, you can reach out to one of our certified online opticians.

How to Improve Vision

Let's go over practical tips on improving eyesight. Knowing proper eye care can save you from future issues.

Good eyesight is one of the most important gifts one can have. Unfortunately, many people don’t realize just how precious it is until they begin to experience vision problems.

That’s why it’s so important that you learn about improving your eyesight now, before it’s too late.

Risk factors and common eye health problems

Your eyes play a critical role in your daily lives, so taking care of them is extremely important. However, eye health problems aren’t always avoidable.

Some people may develop issues due to family history, meaning they’re more likely to contract a specific condition because of genetics.

Age may also be a factor in other eye conditions that can cause severe damage but are not a natural part of aging.

These conditions can often be treated or slowed. However, they may lead to significant vision loss if not detected early.

Other risk factors include chronic health conditions, such as diabetes or high blood pressure. Additionally, studies have shown that certain ethnicities may have a higher risk for developing particular eye problems.

These risk factors make it essential to get routine eye exams and to be aware of what can put you at risk and what symptoms to look out for. Being proactive in this regard can help maintain your eye health now and in the future.

Top tips to improve your eyesight naturally

In this section, we’ll go over practical tips and advice on improving eyesight and potentially slowing damage that may have already occurred.

Know the importance of diet and lifestyle

Taking care of your eyes is essential, and it all starts with diet and lifestyle. Consuming foods rich in omega 3 fatty acids, such as salmon and walnuts, can help improve healthy eyes and sight.

Including leafy greens like spinach and kale, which are rich in lutein and zeaxanthin, adds further protection for your eyes.

Maintaining a healthy weight is also important, as obesity has been shown to increase the risk of diseases like cataracts and glaucoma that cause vision loss.

Vitamins A, C, and E, as well as carotenoids, are essential for healthy vision. These nutrients can be found in colorful fruits and vegetables like carrots, oranges, and bell peppers.

In general, eating the rainbow and a diverse range of fruits and vegetables is very beneficial. Regular eye check-ups with a healthcare provider can help detect any underlying issues early on, allowing for timely intervention.

Avoiding smoking is crucial, as it has been linked to several vision-related problems, including macular degeneration. Hydration, too, plays a vital role, as dry eyes can become a significant discomfort if not addressed through proper fluid intake.

By incorporating these nutrients into your diet and making good lifestyle choices, you can help keep your eyes healthy and functioning optimally for years to come.

Investing in your eye health now can ensure a lifetime of clear vision, enhancing your quality of life in immeasurable ways.

Get regular eye exams and medical care

Your eyes are incredibly important, and they deserve the same level of medical care that you would give to any other part of your body.

Something as simple as an eye exam can help detect early signs of eye diseases, such as glaucoma and age-related macular degeneration, that can lead to permanent vision loss or accelerate vision impairment if left untreated.

During an eye exam, your optometrist or eye doctor will do a full eye health exam to assess not only your vision but all areas of your eye, like the optic nerve.

This is responsible for transmitting visual information to your brain. This examination can uncover issues like optic neuritis, which can be an early sign of more significant health problems.

During an eye exam, your doctor can detect issues that you may not have any symptoms of.

As we age, our vision changes, and we may experience eye strain or other age-related vision changes such as presbyopia, which affects our ability to focus on close objects.

Regular eye exams can help prevent or address these issues, and ensure that you’re taking care of your eyes to the best of your ability.

Additionally, it’s important to recognize that eye health is linked to overall well-being. Chronic health conditions like diabetes or hypertension can affect the eyes, leading to conditions like diabetic retinopathy.

Proper communication between your optometrist and general healthcare provider can help in managing these health challenges and preserving your vision.

Children also benefit from regular eye check-ups. Early detection of vision problems can have a significant impact on a child’s learning and development. Make sure to get yourself and all the family regular check ups.

Protect your eyes

Your eyes are precious and deserve extra care, especially when it comes to protecting them from the sun’s harmful rays.

When you wear sunglasses it is a simple yet effective way to shield your eyes from UV radiation, which can lead to numerous eye problems and discomfort.

Polarized lenses in sunglasses can also reduce glare, making driving or outdoor activities more comfortable and safe.

And let’s not forget the importance of using lenses to protect our eyes from other potential hazards like debris, dust, wind, and even the blue light emitted from screens.

It is key to invest in a good pair of sunglasses. Look for UV400 glasses that block 100% of both UVA and UVB rays for the best protection.

The next time you step out in the sun, whether it’s for a day at the beach or a brisk winter walk, grab your sunglasses to keep your eyes safe and healthy. Your vision is worth the investment.

Follow the 20-20-20 rule

In today’s digital age, we spend countless hours staring at screens, whether it’s for work, leisure, or communication.

However, this habit can take its toll on your eyes, leading to poor vision and discomfort. That’s where the 20-20-20 rule comes in; every 20 minutes, take a 20-second break from your screen and focus on something 20 feet away.

This short break can alleviate eye strain and prevent potential eye damage in the long run. Next time you find yourself glued to your screen, remember to take a quick break and give your eyes the rest they deserve.

DID YOU KNOW?

Blue light glasses are also something to consider when investing in eye protection. They can block harmful blue light and reduce squinting at your screen.

Know your family's medical history

One of the most important things you can do to protect your health is to know your family’s medical history. Your family’s health history can give you insights into what sort of health issues you might have to contend with in the future.

Eye problems can run in families, and knowing your family’s history can help you take steps to protect your vision.

For example, if you have a family history of glaucoma, you may need to get your eyes checked more frequently as you age. Similarly, if you have a history of cataracts in your family, you might need to start taking steps to protect your vision from an early on.

Take the time to talk to your family members about their health experiences eye-related and otherwise. It could make a big difference to your own health in the long run.

Treatment of eye conditions if problems arise

When it comes to keeping your eyes healthy, early diagnosis is key. This is especially true for eye diseases. If you do experience any symptoms of an eye condition, such as blurry vision or eye pain, it’s important to seek medical attention as soon as possible.

Modern medicine has made incredible strides in the field of ophthalmology, so there are many treatment options available.

Depending on the condition, you may need to undergo eye surgery or simply manage your symptoms with medication or lifestyle changes. Regardless of the specific treatment, the most important thing is to address any eye problems as soon as possible.

If there are no surgical corrections to make, your doctor may prescribe you glasses or contacts to improve your vision.

Importance of healthy vision

Vision is one of the most important senses that we possess. It’s how we perceive the world and navigate your surroundings. Maintaining healthy vision is crucial for overall well-being.

Poor vision can impact our ability to perform daily tasks as well as cause other ailments like headaches, dizziness, and fatigue.

Regular eye exams and adopting good habits, such as taking breaks from electronic screens and always wearing your prescription glasses and contact lenses, can help protect your eyes and preserve your vision.

Eye health is invaluable; taking necessary steps to protect it can improve your vision as well as slow genetic and age-related conditions. Visit our Optical Center for more informative eye care articles.

Eye Irritation From Contact Lenses

Eye Irritation From Contact Lenses

Don’t let eye irritation keep you from wearing contact lenses, find out how to avoid discomfort from contacts.

When it comes to vision correction, contact lenses are very convenient. They are the preferred choice of many people who want clear vision without having to wear eyeglasses.

Contact lenses have come a long way since they were first introduced, and are now much more advanced, comfortable, and accessible.

The earliest versions of contact lenses were blown from glass and were quite large and heavy, making them far less popular than wearing glasses.

Contact lenses are worn directly on the front surface of the eye, known as the cornea, and adhere to the shape of the eye. Because of this, they offer a more natural and broader field of vision.

While contacts are an excellent choice for many, some people may experience discomfort from wearing them.

Most problems can be treated with a bit of attention and knowledge, but if you experience pain or changes in vision, it’s best to contact your eye doctor immediately.

Do contacts hurt?

Contact lenses, if worn and fitted correctly, should not hurt your eyes. Like most things, they may take a little time to get used to.

If you’re new to wearing contacts or have switched to a new brand or prescription, you may initially experience minor eye irritation. This irritation should only last a few days as your eyes are adjusting.

A glasses prescription and a contact lens prescription are different. It is important to note that you must see an eye care professional for an updated prescription before using contacts.

Wearing contact lenses with the wrong prescription can lead to symptoms such as blurry vision, headaches, eye strain or fatigue, and eye pain (AAO, 2012).

What causes contact lens discomfort?

There are several reasons why you may experience discomfort from your contact lenses. Understanding the reason is the first step in alleviating the irritation.

Poorly fitted lenses

Everyone’s eyes are different—different shapes, needs, and prescriptions. To ensure you are wearing the correct lenses, it is essential to have an eye exam with an eye doctor so they can write a prescription to accommodate your eyes and vision needs.

The diameter and base curve of a contact lens are two measurements that affect how the lens will fit your eye. The base curve is the measurement of the back curvature of the contact lens.

A person with a more rounded cornea needs a steeper contact lens. A person with a less rounded cornea needs a flatter contact lens.

The diameter of a contact lens is the width of the lens from edge to edge. When you wear a contact lens with the appropriate diameter, the lens will remain stable on your eye.

A contact lens with the wrong diameter can cause discomfort and may even fall out.

Allergies

Allergies are a common cause of irritated eyes for those wearing contacts. If you suffer from allergies and wear the same contacts daily, your eyes may hurt as environmental allergens like pollen, pet dander, and dust build up on your contact lenses.

Contact wearers who have eye allergies may experience itchy, dry, or watery eyes. To avoid this irritation, some people may wear daily disposable lenses to ensure nothing has built up on the lens.

Another option is temporarily wearing glasses to give your eyes time to rest.

Dry eyes

Another common cause of irritation is dry eye. If your body does not produce enough tears, your eyes may become dry. Tears keep the eyes moist, protecting them from irritants and supplying nutrients.

You don’t need to cry to get the benefits; healthy eyes regularly produce tears. The benefits of tears are essential for anyone, but they can be especially helpful if you wear contacts.

While contact lenses allow oxygen and moisture to pass through to the eyes, bare eyes allow more through. If you’re experiencing discomfort from dry eyes, lubricating eye drops or artificial tears can help restore moisture.

If irritation persists, please see your eye care professional.

An eye infection

Wearing contacts will most likely worsen the symptoms if your eye becomes infected. A common eye infection among contact wearers is keratitis. Keratitis is an inflammation of the cornea, the clear tissue on the front of your eye.

If you are suffering from an eye infection, you should seek treatment from your eye doctor and avoid wearing contact lenses while your eye is healing.

A scratched eye

A scratch on your cornea may cause eye pain and lead to a more serious eye condition. If you think your eye has been scratched, it is important to see an eye care professional and wear glasses until your eye doctor confirms you can wear contact lenses again.

To avoid a scratched eye from a contact lens, take proper care of your lenses and follow the instructions for wearing and replacing them.

Dirty contact lenses

As allergens may build up on your lenses, dirt, dust, and other materials may also accumulate. Unless you wear daily wear lenses, regular cleaning and disinfecting with a proper contact lens solution are essential for keeping your eyes healthy.

Cleaning contacts does not take much time and should be a priority when taking your lenses out for the day. Be sure to use the correct contact lens solution for your type of contacts. Here are some tips on how to clean your lenses properly:

Wash your hands
Fill your contact lens case with the proper contact solution (ensure it is fresh solution)
Put the lens and more solution in the palm of your hand and rub the lens for about 15 seconds
Rinse the lens with more solution
Place the lens in the contact lens case and close it
Repeat with the other lens

Old contacts

Contact lenses do expire, and you should never wear expired lenses as they become more exposed to bacteria. Wearing old contact lenses can irritate the eyes and cause further discomfort, irritation, and problems.

Before putting in contact lenses, check the expiration date. If your lenses are expired, be sure to get new ones to avoid complications.

Symptoms of eye irritation from contact lenses

Symptoms may vary from person to person and depend on the cause of the discomfort. Generally, symptoms of eye irritation from contact lenses include burning, stinging, or itchy eyes.

Some wearers might feel that a foreign body is stuck in the eye, like an eyelash or a piece of dirt. Other symptoms may include unusual eye secretions, redness, reduced sharpness of vision, blurred vision, and light sensitivity.

Eye health should always be a priority. If you’re experiencing discomfort or pain persists, contact your eye doctor immediately.

DID YOU KNOW?

Contact lenses should not cause discomfort or irritation when used and worn correctly.

How to relieve contact lens discomfort

To avoid eye irritation, you can take a few measures to find relief. The first is always to make sure to clean your lenses properly. Cleaning your contacts with the proper solution will keep dirt, dust, and other objects off your lenses and out of your eyes.

Before putting in contacts, wash your hands. Use soap and tap water to ensure your hands are clean before touching your contacts or eyes. If your lenses are scratched, expired, or ruined somehow, do not wear them.

As always, speaking with your eye doctor is the best way to understand the cause of the irritation and how to address it.

Can contact lenses cause an eye infection?

While rare, it is possible that contact lenses can cause eye infections.

Certain things may increase the chances of getting an eye infection, including using extended-wear contact lenses, sleeping in your contacts, dirty lenses or lens cases, and having dirt or bacteria accumulate on the lenses.

You should also avoid showering, swimming, or bathing in contact lenses. Swimming with contacts increases your risk of irritation and even infection.

How to take care of your contact lenses

Taking proper care of your contact lenses is essential in avoiding eye irritation and infections. Proper handling, cleaning, storage, and use of your contacts are crucial. A contact lens is delicate, so treat it carefully to avoid bending or tearing it.

Before touching your contact lenses, thoroughly wash and dry your hands. Be sure to clean the lenses and the case regularly with a solution appropriate for your lenses and never reuse or mix solutions.

Wearing contact lenses has plenty of benefits, and they’re a great option for vision correction. Contacts are a preferred choice for many as they won’t obstruct your view or stop you from playing sports and competing in outdoor activities.

With a bit of care for and attention to your lenses and eyes, there is no reason why you should ditch them for a pair of glasses.

If you have any questions about contact lenses and how to care for them, head to our Optical Center to speak with one of our in-house opticians today.

LASIK Eye Surgery

If you're tired of wearing glasses or contact lenses, laser-assisted in situ keratomileusis - better known as LASIK - surgery may be the solution for you.

Disclaimer: We at SmartBuyGlasses are not medical doctors. This article contains general information and advice. Speak to your eye doctor to find out if you are a suitable candidate for LASIK and what kind of results you can expect.

What is LASIK eye surgery?

Refractive surgery is the broad term for surgical procedures that correct vision problems, and the LASIK technique is the most commonly performed one. During LASIK surgery, an excimer laser is used to reshape the transparent tissue (cornea) at the front of the eye so that light focuses directly on the retina at the back of the eye.

The eye refracts (bends) light as it enters the eye, and for normal vision, the focal point of the light rays must be precisely on the retina. In eyes with a refractive error such as myopia, hyperopia, or astigmatism, this is not the case, resulting in blurred vision.

LASIK eye surgery addresses this issue by modifying the shape of the cornea so that light rays are refracted correctly, thus providing clear vision. After LASIK surgery, patients can enjoy sharp visual acuity and a greater quality of life, without the need for glasses or contact lenses.

After LASIK surgery, patients can enjoy sharp visual acuity and a greater quality of life, without the need for glasses or contact lenses.

What conditions can LASIK eye surgery treat?

LASIK surgery is used to treat refractive errors, which are the most common causes of vision problems. The three most common refractive errors are myopia, hyperopia, and astigmatism.

In each case, light is refracted incorrectly but in different ways. If you have one of these conditions, refractive eye surgery may be effective in improving vision, as long as it falls within the treatment limits.

Myopia

Myopia, also known as shortsightedness and nearsightedness, is the most common vision problem in the world, affecting about 33% of the global population. People with shortsightedness have no problem with their close-up vision, but experience blurred vision when looking at distant objects.

With a nearsighted eye, the eyeball itself is elongated, causing the focal point of the light rays entering the eye to fall short of the retina. An overly-curved cornea can also have this effect, with the same vision results.

Hyperopia

Hyperopia is commonly referred to as farsightedness, and, as the name suggests, is the inverse of nearsightedness. People with hyperopia have clear distance vision, but nearby objects appear fuzzy or blurry. An eyeball that is short in length is the cause of hyperopia, focusing light rays beyond the retina.

An eyeball that is short in length is the cause of hyperopia, focusing light rays beyond the retina.

Astigmatism

People affected by this refractive error have blurry vision both up close and farther away. An irregularly shaped cornea or lens is responsible for astigmatism.

Does LASIK eye surgery permanently correct your vision?

LASIK surgery alters the shape of your cornea, based on your vision requirements at the time of your surgery. This is a permanent change, and the corneal tissue will never revert to its previous shape. However, due to the natural aging process of the eyes, your vision will likely begin to deteriorate at some point, possibly necessitating glasses again.

Presbyopia is a condition affecting close-distance vision, and it tends to develop in most adults from the age of 40 onwards, again, as a natural part of aging. Even after a LASIK procedure, you’ll probably need to use reading glasses at some stage to treat presbyopia, but this will likely be years later.

Vision changes that occur after having refractive surgery are not an indication that the procedure has not worked, but a consequence of unrelated conditions that may develop afterwards. Many patients enjoy consistent vision for ten years or more following surgery (Ide et al., 2014).

Many patients enjoy consistent vision for ten years or more following surgery (Ide et al., 2014).

Who is a good candidate for LASIK eye surgery?

Laser vision correction is not a suitable option for everyone. Even if you have a refractive error, there is no guarantee that the specifics of your condition will make it a viable option for you. You must also meet the following criteria in order to have the procedure:

You must be at least 18 years old, although it is better to wait until you’re in your 20s when your vision is more likely to have stabilized
Your vision prescription should have remained constant for at least the last year
Your corneas must be thick and healthy, and you must have healthy eyes in general
You need to have realistic expectations about what LASIK can do for your vision

Unsuitable candidates

Even if you satisfy the requirements mentioned above, there are, unfortunately, some factors that can directly rule out the possibility of undergoing LASIK surgery. If any of the following apply to you, LASIK may not be a feasible option:

Your refractive error is unstable (still worsening)
You have extreme myopia, hyperopia, or astigmatism
You suffer from severe dry eye syndrome
You have overly thin corneas
You have scars on your corneal tissue
You have keratoconus (cone-shaped corneas)
You have advanced glaucoma
You have cataracts
You have a history of certain eye conditions
You have diabetes that is not well controlled

Preparation for LASIK eye surgery

The first thing you need to do when considering LASIK surgery is to speak with an opthalmologist. They will be able to tell you to what extent the surgical procedure could be effective in your case, and give you realistic expectations for the outcome. They will then test your vision thoroughly to ensure you are a good candidate.

For those who wear contact lenses, you’ll have to take a break from them and wear glasses only for a few weeks before the eye doctor evaluates your potential as a candidate. The exact duration will depend on the type of contact lenses you wear and how long you’ve been using them. Your eye doctor will give you precise guidelines for this.

The opthalmologist will then check for the presence of other eye problems by means of a comprehensive eye exam. If there are no complications, they will then map the surface of your cornea (corneal topography) and check its thickness, as well as measure your pupils. These details are important for programming the computer used for laser surgery.

The procedure

During laser eye surgery, the ophthalmologist or refractive surgeon will use eye drops to numb your eyes. They will then place a suction ring and eyelid speculum in your eye. These devices do not cause any pain, but you may feel some pressure from them. They hold your eyes in the correct position while also preventing you from blinking.

Using a laser or a device called a microkeratome, the eye surgeon will make an incision in your corneal tissue to create a thin flap, which is then folded back. You will be asked to stare at a fixed point ahead of you while the eye surgeon uses the laser to reshape your cornea according to the measurements taken by your ophthalmologist.

During this part of the procedure, you will hear a clicking sound and notice a strange odor. This is no cause for alarm, just a normal part of the laser treatment. The smell is created by the chemical reaction from the laser beam shaping the cornea.

Once the reshaping is complete, the eye surgeon will fold the corneal flap back over to its original position, where it will reattach by itself within two to three minutes and begin to heal.

Aftercare

You’ll be able to see after surgery, and your old corrective lenses won’t be effective anymore, but it will take two to three months for your vision to fully sharpen and stabilize. Patients usually experience a gritty, itchy, or burning sensation in their eyes immediately after laser surgery. You may be given eye drops or pain medication to use in the hours and days that follow.

You’ll have a follow-up appointment with your eye surgeon within a day or two of your surgery. They will check your condition and give you precise recommendations which must be closely followed throughout the healing process.

You’ll receive a protective shield to wear on your eyes while sleeping to avoid unwanted contact and prevent infection. This can be used for several weeks until the eyes heal. It’s essential to refrain from touching your eyes even in the daytime to allow the corneal flap to heal correctly.

You may have some pain, dry or watery eyes, puffy eyelids, or increased light sensitivity in the first week or so after laser eye surgery. You may also see a halo around bright lights for a while. This is normal and will subside with time. Eye drops can be effective in relieving dry eyes, but if you feel severe pain or that these symptoms are not improving as they should, consult your eye doctor.

Some activities pose risks to the healing process, so you may have to modify your regular routine for a little while after your procedure. It’s generally advised to avoid exercise for three days and refrain from playing contact sports for the first month post-op. Don’t use eye makeup or cosmetic products on or near the eyes for two weeks, and stay away from hot tubs for two months.

If you have doubts about any other activities that are a regular part of your lifestyle, ask your eye doctor’s advice and follow the time guidelines they give you.

DID YOU KNOW?

The procedure usually only takes about 5 minutes per eye, with the actual laser treatment generally taking 5-15 seconds per eye.

What are the risks and side effects associated with LASIK?

There are risks associated with every kind of surgery, and refractive surgery is no different. The initial side effects mentioned in the section above generally go away after a week or two, but in some cases, they may continue for longer. Changing vision throughout the day is another initial side effect that can persist for some people.

Apart from standard side effects, there is the risk of complications stemming from laser eye surgery. Over 99% of patients do not experience any, according to the Cleveland Clinic, but it is useful to be aware of them.

Issues could arise with the cornea, potentially requiring treatment or surgery
Inflammation or infection of the eye could occur, which can be treated with medication
Eyesight that is worse than your pre-LASIK vision, usually untreatable

It is very rare that LASIK patients experience vision loss as a result of refractive surgery, but it is still possible. The risk of any surgical complications occurring with LASIK is less than 1%. There is always the risk that you may be disappointed with the results, especially if your expectations are too high, or if you’re hoping to never again have to wear contact lenses or glasses.

Is LASIK eye surgery right for me?

Refractive surgery can be a life-changing procedure, allowing people to live more freely without having to worry about glasses or contact lenses. Many activities become much easier and more comfortable, such as water and contact sports, as well as the simple fact of waking up in the morning and being able to see immediately, without having to reach for your glasses or contact lenses.

As outlined in this article, having laser eye surgery is not simply a matter of deciding whether you want it or not. There are many criteria that must be met in terms of your eye and personal health, as well as the changes it will have to your personal life during the recovery period, and of course, the financial aspect.

Speak to your eye doctor about laser refractive surgery; they will be able to talk to you in detail about your concerns, and have the relevant knowledge of your existing medical conditions, your medical history, and how it could be beneficial for you personally. In the meantime, feel free to ask our Opticians if you have any other inquiries about LASIK surgery or general eye health.

What Causes Tunnel Vision (Peripheral Vision Loss)

Do you ever feel like your world is slowly shrinking? You’re not alone. Tunnel vision is something that many people suffer from for various reasons.

Disclaimer: We at SmartBuyGlasses are not medical doctors. This article contains general advice. If you experience tunnel vision, please consult your doctor or an eye care professional for treatment.

What is tunnel vision or PVL?

Tunnel vision, also known as Peripheral Vision Loss (PVL), is a medical condition where an individual experiences a narrowed field of vision. This condition can occur due to various reasons, such as optic nerve damage or brain injuries.

When tunnel vision occurs, people may find it difficult to see objects on the peripheries of their field of vision and might have trouble with activities that require them to scan their surroundings.

While for some individuals, tunnel vision develops over time, others may experience it suddenly due to an underlying medical condition. Although it’s not always treatable, there are various aids and treatments available to help people with PVL cope with the changes in their vision.

What is an example of tunnel vision?

Tunnel vision is a term used to describe a type of visual impairment where the individual’s side vision is severely reduced, resulting in a narrow visual field. This can lead to a person feeling as though they are looking through a tunnel, with everything outside the tunnel being blurry or completely out of sight.

What causes tunnel vision?

The causes of tunnel vision or tubular vision can vary from person to person and can be brought about by both physical and psychological factors. Physically, it can be caused by eye diseases such as glaucoma, cataracts, or retinitis pigmentosa, among others.

On the other hand, psychological causes such as panic attacks can also trigger tunnel vision as a way of the body protecting itself from a perceived threat.

Migraine

Migraines can cause a range of visual disturbances, including tunnel vision, compromised vision on one side or total vision loss. Migraines can result from various ocular and nervous stimuli and can last anywhere from 10 minutes to multiple hours.

Retinal detachment

Retinal detachment occurs when the retina, located at the back of the eye, separates from the underlying tissue. The optic nerve, responsible for transmitting visual information to the brain, is directly impacted by retinal detachment, resulting in tunnel vision. Any changes in vision should be immediately evaluated by an eye care professional through a comprehensive dilated eye exam.

Glaucoma

Glaucoma is a medical condition that affects the eyes. It is caused by a buildup of pressure from excess fluid within the eye, which can result in peripheral vision loss. Glaucoma can lead to loss of vision if it’s not diagnosed and treated early.

Stroke

A stroke is a medical condition that occurs when the blood supply to part of the brain is reduced. It can happen when blood vessels in the brain are blocked. One of the first symptoms of a stroke is loss to peripheral vision, resulting in a concentration on the central visual field.

Symptoms of tunnel vision

Tunnel vision affects an individual’s peripheral vision, causing them to see only a narrow channel while the rest of the surroundings become blurred or invisible. The symptoms are usually gradual and can go unnoticed at first.

If you start experiencing visual disturbances such as difficulty focusing on objects that are outside of your central vision, altered night vision or are having a hard time adjusting to dim lights, you may be experiencing tunnel vision symptoms.

Other symptoms include eye fatigue and headaches, especially when trying to focus for an extended period. In extreme cases, tunnel vision can cause a complete loss of peripheral vision, resulting in difficulty with balance. It is vital to consult a specialist or eye doctor if you believe you may be experiencing tunnel vision symptoms.

Is tunnel vision a symptom of anxiety?

When it comes to anxiety, there are a multitude of symptoms that can manifest themselves in different ways. One of these symptoms that people may experience is tunnel vision. It is important to remember that it is a common symptom of anxiety and can be managed with the right tools and techniques.

These could include things like deep breathing exercises, meditation, or talking to a mental health professional to work through the root causes of your anxiety. Overall, it is important to remember that tunnel vision is just one symptom of anxiety, and with the right support and resources, you can learn to manage and overcome it.

How do you treat tunnel vision?

We recommend that you consult your eyecare professional to discuss the treatment of tunnel vision as there are many factors to consider. Overall, when your doctor decides a course of treatment for tunnel vision, they will address the underlying cause.

Depending on the cause, they may recommend medications, surgery, or lifestyle changes. For example, if your tunnel vision is caused by high blood pressure, you may be prescribed medication to control your blood pressure.

If it is caused by a migraine, your doctor may recommend migraine medication or lifestyle changes such as reducing stress, eating a healthy diet and getting regular exercise. Whatever the cause may be, it is vital to seek medical attention. This can be a serious condition so your doctor will take a course of action to suit the severity of your case.

DID YOU KNOW?

Tunnel vision is caused by a number of health problems. Addressing the cause of this visual disturbance as soon as possible will help you make a faster recovery.

Is PVL or tunnel vision permanent?

The good news is PVL does not usually result in permanent vision loss. It’s a transient condition that occurs due to a variety of causes. It’s not uncommon to experience PVL or tunnel vision during high-pressure situations like exams or job interviews.

However, it’s important to seek medical help if you experience PVL or tunnel vision frequently, as it could be a symptom of an underlying medical condition. Remember, taking care of your mental and physical health is extremely important, and seeking professional help when needed is nothing to be ashamed of.

How to reduce the risk of tunnel vision

Our eyesight is precious, and it’s important to take steps to protect it. One potential threat to healthy vision is tunnel vision. Fortunately, there are steps you can take to reduce the risk of developing tunnel vision.

Firstly, make sure you know your family’s eye health history and visit the eye doctor regularly. Secondly, ensure that your workspace is well-lit, as dimly lit environments can cause undue strain on your eyes.

Finally, consider a well-balanced and nutritious diet that includes plenty of eye-healthy vitamins and make lifestyle choices to optimize personal health, such as avoiding smoking.

When to see a professional

Seeking help early on can often make the biggest difference in long-term outcomes. If you’re experiencing persistent symptoms or concerns that are affecting your daily life, it’s worth reaching out to a professional as soon as possible for support.

They can help you better understand your condition and provide appropriate treatments or referrals to specialists if necessary. At SmartBuyGlasses Optical Center, we are here to reassure you with the facts so you can make informed choices about your health before visiting a doctor.

What Does 20/20 Vision Mean?

Ask our opticians

Ask now

Discover what 20/20 vision means and how it relates to normal eyesight.

SUMMARY

20/20 vision refers to normal visual acuity, meaning that you can see an object clearly from the standard distance for eye tests (20 feet away).

Since it only measures the clarity of distance vision, it doesn’t necessarily mean perfect eyesight, although people with 20/20 vision typically don’t require glasses.

Have you ever heard this term and wondered “what does 20/20 vision mean?” This article provides the explanation you’ve been looking for.

20/20 vision means that you can see an object clearly 20 feet (6m) away. It is a term used to indicate visual acuity (how clearly you can see).

For example, if you have 20/30 vision, that means that you can see at 30 feet (9m) what an average person with normal vision can see at 20 feet. In short, 20/20 vision is normal visual acuity.

Keep in mind that 20/20 vision is a term used mainly in the United States. In other countries, eye care professionals may say 6/6 vision instead, as the measurements are in meters and not feet.

Visual acuity

Visual acuity refers to the clarity or sharpness of vision. To measure visual acuity, eye doctors use a standard Snellen chart during an eye exam. The Snellen chart consists of several rows of letters, with the letters in each row decreasing in size from top to bottom.

During a visual acuity test, an individual is typically positioned at a distance of 20 feet (6 meters) from the eye chart. The person is asked to cover one eye while reading the letters on the chart aloud, starting from the top row and moving down until they can no longer accurately identify the letters. The test is then repeated with the other eye.

The results of the test are recorded as a fraction, with the numerator (first part of the fraction) representing the distance at which the test was conducted (usually 20 feet or 6 meters) and the denominator (second part of the fraction) representing the distance at which a person with normal visual acuity can read the line correctly.

Does having 20/20 vision mean you have perfect vision?

Having 20/20 vision does not necessarily mean that a person has perfect vision, although it is often considered to be within the normal range of visual acuity.

Visual acuity is just one aspect of overall visual function. Other factors contribute to the quality of vision, such as depth perception, color vision, peripheral vision, and the ability to focus and track objects smoothly.

Additionally, visual acuity alone does not provide information about the health of the eyes or any underlying eye conditions.

To assess overall vision, eye care professionals conduct comprehensive eye examinations that evaluate various aspects of visual function, eye health, and potential eye conditions.

So, while 20/20 vision is generally considered to be good, it does not guarantee perfect vision or exclude the possibility of other vision-related issues.

DID YOU KNOW?

The fact that you might have 20/20 vision is a good thing, but does not imply that your vision is perfect. Many other factors need to be taken into consideration when assessing your eyesight.

What causes you to have less than 20/20 vision?

Refractive errors and some eye conditions might cause an individual to have less than 20/20 vision, and therefore the need for vision correction. These include:

Myopia
Hyperopia
Astigmatism
Presbyopia
Eye diseases
Eye injuries or trauma

Additionally, systemic health conditions, medications, or genetic factors may also play a role in vision impairment. It’s important to note that the specific cause of reduced visual acuity can vary from person to person.

If you are experiencing a decrease in visual acuity or have concerns about your vision, it is recommended to consult with an eye care professional who can perform a comprehensive eye examination and provide a proper diagnosis.

If you have 20/20 vision, do you need glasses?

If you have 20/20 vision, it generally means that you have normal visual acuity and can see at 20 feet (6m) what a person with normal vision can see at 20 feet (6m). In most cases, individuals with 20/20 vision do not require glasses for clear-distance vision.

However, it’s important to note that visual acuity is just one aspect of overall visual function. Even for people with 20/20 vision, glasses, contact lenses, or prescription sunglasses may still be required to correct vision for other visual needs.

When should I go for a vision test?

Eye exams are important for your overall health and well-being, just like any other regular check-up. By taking care of your eyes, you’ll make sure to detect any need for vision correction or identify issues and get the right treatment for them.

Routine eye exams: It is generally recommended for adults with no known eye conditions or risk factors to have a comprehensive eye exam every 1-2 years.
Children: Children should have their first comprehensive eye exam at around 6 months of age, followed by additional exams at age 3, before starting school, then once a year from age 5-13, and every two years from then on. Regular eye exams in childhood are crucial for identifying and addressing vision problems that can affect learning and development. vision.
Specific concerns or risk factors: If you have specific concerns about your vision or have risk factors for eye conditions, it is recommended to have a vision test.
Regular follow-up exams: If you have already been diagnosed with an eye condition, wear corrective lenses, or have undergone eye surgery, follow the recommended schedule of regular check-ups and follow-up exams as advised by your eye care professional.
Age-related changes: As you age, your risk of developing age-related eye conditions such as presbyopia, cataracts, glaucoma, and age-related macular degeneration increases. Regular eye exams become particularly important for individuals over the age of 40 to monitor and manage any changes in vision or eye health.

Remember that these are general guidelines, and individual circumstances may vary. It’s always best to consult with an eye care professional who can assess your specific needs and provide personalized recommendations on when to go for a vision test based on your age, health, and risk factors.

Eye Anatomy

Our eyes are made up of many parts that work together with the brain. They are critical in helping us interact with the world.

SUMMARY

The eye is a complex organ of the body.

The key parts include the cornea, lens, retina, and optic nerve; each plays a role in capturing and processing light.

By understanding how the eye works, you can better recognize symptoms of vision problems and maintain eye health.

Human beings have five senses, sight being one of them. Eyes are responsible for giving us the sense of vision and allow us to see and experience all the beauty that surrounds us.

One of the most important organs in the body, eyes play a major role in day-to-day life and experiences. “Eyes are the windows to the soul” is an expression that is often used to describe the deep connection we feel when making eye contact with someone.

It is through our eyes and the sense of sight that we are able to connect with people, places, and things. Small but mighty, it is essential to keep our eyes healthy. Most people tend to take sight for granted, without giving much thought to how it is all made possible.

What makes up an eye?

The human eye is a complex organ that enables us to perceive the world around us by capturing and processing light. The eye is made up of many light-sensitive cells and works in conjunction with the brain to provide us with the sense of vision.

Eyeballs are shaped like spheres and sit in a protective socket called the orbit. The eyeball consists of three layers that surround a clear jelly. This jelly, known as the vitreous, is inside the eye and helps maintain its shape.

The outer layer of the eye consists of the sclera and the cornea. The iris, pupil, and crystalline lens (lens) are in the middle layer. And the innermost layer of the human eye is called the retina. Here is a quick breakdown of those main structures:

Cornea – the transparent structure at the front of the eye
Sclera – the white part of the eye that surrounds the iris
Iris – the colored portion of the eye
Pupil – the black circle in the center of the iris
Lens – responsible for focusing light and images
Retina – the light sensitive tissue at the back of the eye

How does the eye work?

The eye is attached to six muscles that control eye movement. One muscle moves the eye right, one to the left, and the other four move the eye up, down, and on an angle.

Human eyes can see about 200 degrees in all directions, including in front of them and to the sides (AAO, 2023). The anatomy of the eye is complex, allowing us to see images, movement, depth, and millions of colors.

The different parts of the eye work together to send visual information to the brain. When we see an object, we are actually seeing light reflecting off that object.

Sight starts at the cornea and ends in the brain. Light passes through the cornea to the lens. Here, light is focused on the retina. When light reaches the retina, at the back of the eye, images are changed into signals and sent through the optic nerve to the brain, allowing us to comprehend these images.

Each component of the surface, the middle, and the inner layers has a role to play in the whole process, all working together, be it directly or indirectly.

The surface of the eye

The surface of the eye is covered with a clear membrane called the conjunctiva and is protected by the eyelids. Our eyelids are folds of tissue that are also lined with conjunctiva.

Eyelids are vital in keeping the cornea moist and protecting the eyes from foreign objects and bright light or excess light. During waking hours, they lay mucous over the eyes, and during sleep prevent evaporation of the mucous.

Behind the cornea is the anterior chamber. The anterior chamber is filled with a fluid called aqueous humor.

Aqueous humor is constantly produced and drained from the eye to maintain normal eye pressure. The aqueous humor also provides nutrients to the lens and cornea, which do not have blood vessels (AAO, 2023).

DID YOU KNOW?

Our eyes have over two million moving parts and contain our body’s most active muscles (CAO, 2023).

The middle layer of the eye

The iris and pupil are located behind the anterior chamber in the central portion of the eye. They work together to control the amount of light that reaches the lens. The lens is directly behind the pupil and its main function is to focus light towards the back of the eye.

Similar to a camera, the eye can adjust the amount of light that enters so that it can function in different lighting conditions, from dim to very bright light.

The aperture control on your camera will let more or less light in depending on the surrounding environment. In our eyes, muscles in the iris dilate (widen) or constrict (narrow) the pupil to control how much light enters the lens.

The ciliary body is located behind the iris and has small muscles that are attached to the lens. Together with the zonules, tiny thread-like fibers that hold the eye’s lens in place, these muscles allow the lens to change shape and focus on near or far objects.

When our eyes look at something very close to us, the zonules loosen and the lens thickens. When the eye looks at images far away, the muscles relax, the zonules tighten, and the lens decreases in thickness. This causes images far away to come into focus.

Unlike a camera lens, which moves closer or further from an object to focus, the human lens does not move position but changes shape. When looking at a distant object, the lens becomes flattened. On the other hand, when looking at an object up close, the lens becomes rounded.

The iris and pupil are located behind the anterior chamber in the central portion of the eye. They work together to control the amount of light that reaches the lens.

The lens is directly behind the pupil and its main function is to focus light towards the back of the eye.

Similar to a camera, the eye can adjust the amount of light that enters so that it can function in different lighting conditions, from dim to very bright light.

When looking at a distant object, the lens becomes flattened. On the other hand, when looking at an object up close, the lens becomes rounded.

After the lens focuses incoming light rays it reflects it on the retina. Refractive errors like farsightedness or nearsightedness occur when the lens improperly focuses images on the retina.

If the lens focuses light behind the retina, this leads to farsightedness. If the lens focuses light in front of the retina, nearsightedness occurs. You must speak with an eye doctor should you notice any differences in your vision. Prescription glasses or contact lenses may help in correcting these issues.

The inner layer of the eye

Once the retina senses the light from the lens, it is responsible for converting it into electrical signals to send to the brain. The retina comprises two parts, the macula, and the peripheral retina.

In the center, the macula processes most of what is directly in view, or your central vision. The peripheral retina is responsible for your peripheral vision.

The retina is made up of many different light-sensitive cells. Photoreceptors are a type of cell that turn light into an electric signal so the brain can compute images.

Rods and cones are photoreceptors that work together to give a clear picture of what you’re seeing. Rods are sensitive to light and allow us to see in low-light conditions. Cones perceive color and fine details and provide a sharp, accurate image (AAO, 2023).

These electrical impulses are sent through the optic nerve to the visual cortex, the part of the brain responsible for sight. The optic nerve is made up of millions of nerve fibers and is essential in transmitting all visual information, including brightness, perception, color, and contrast (AAO, 2023).

What conditions affect how the eyes work?

Various conditions can affect how our eyes function. Common vision problems like nearsightedness, farsightedness, and astigmatism, as well as eye injuries, are among these issues.

Problems with the muscles in the eyes are common. Strabismus (crossed eyes) or amblyopia (lazy eye) can lead to physical and visual changes in the eye.

As we age, our eyes may change. Many people begin to lose close-range vision around the age of 45 (Cleveland Clinic, 2021) and may develop presbyopia. The lens may start to deteriorate and lead to the need for reading glasses. In more severe cases, a cloudy lens may be replaced with an intraocular lens through surgery.

Common problems like infection or irritation can cause redness, swelling, or discomfort. If you notice changes in your vision or eyes, contact your eye doctor for a check-up.

How can I keep my eyes healthy?

Eye anatomy is complex, and we must take care of our eyes in order for everything to function correctly. It is crucial to see an eye doctor regularly for eye exams to maintain eye health. If required and prescribed, wearing corrective lenses is vital to prevent further damage.

If you spend a lot of time in front of digital screens, consider wearing computer glasses or taking breaks and doing eye exercises. When outside, sunglasses with proper UV protection are essential.

Always wear protective eyewear during contact sports or if you have a job working with tools that could potentially lead to eye injuries.

If you have any questions about maintaining eye health, head to our Optical Center and speak to one of our certified Opticians.

Eye Shapes

Discover the 10 different eye shapes, how they impact eyesight and how to find the best frames to suit you.

If you were asked to describe what someone looks like, what features would you include in your description? For many, eye color would be one of the first things mentioned. It is a very noticeable aspect of a person’s look, and is often the first thing that strikes us when meeting someone new.

Although it receives less attention, there is another ocular trait that impacts physical appearance and natural beauty; eye shape. You may have noticed someone has particularly wide, deep-set, or narrow eyes, but did you know there are actually ten different eye shapes that categorize this facial feature?

The 10 Different Eye Shapes

As opposed to face shapes (which are very loosely divided into four different options), eye shapes are defined in more detail, as evidenced by the larger number of categories.

The eye length, openness and angle of the eyes are among some factors involved in the classification of different eye shapes.

These small details are perhaps not something you consciously recognize, but they definitely have an effect on our overall perception of people’s faces.

Almond eyes

The defining characteristic of almond shaped eyes is that the iris touches both the top and bottom eyelid. This means that the sclera (the white part of the eye) is not visible directly above or directly below the iris, which touches both the upper and lower lash line.

As the name suggests, almond eyes have an elongated, oval/almond shape and taper off significantly towards the corners.

Round eyes

With round eyes, the white of the eye is visible both above and below the iris, which can make them stand out more.

The inner and outer corners have a less prominent taper than that of an almond eye shape. Round eyes also have a visible crease in the skin of the upper eyelid.

Protruding eyes

Some people’s eyeballs are naturally set further forward in the eye socket. The result of this is protruding eyes. The shape of the eyeball itself is more prominent, making the eyes look rounder.

The outer edges of protruding eyes are generally wider than those of most eye shapes. This means a large part of the sclera is visible, as the eyelids usually do not reach the iris.

Monolid eyes

The eyelids are the determining factor here, as they have no crease or fold. This sets monolid eyes apart from other eye shapes and gives them a very distinct appearance.

The monolid eye shape appears flat as the upper lid sits smoothly above the eyeball, rather than cling tightly to form a crease. This is also known as an epicanthal fold.

Downturned eyes

The main characteristic of downturned eyes is notable in the outer corners of the eyes. With most eye shapes, the outer corner is slightly higher than the inner corner. With downturned eyes, it is level with, or slightly lower than the inner corner.

The outer edge of the upper eyelid can also slope downwards more steeply than with other eye shapes.

Upturned eyes

Unsurprisingly, upturned eyes are the opposite of downturned eyes. In this case, the outer corner is positioned higher than the inner corner.

The overall shape is similar to almond eyes, but with the added lift in the outer corner. Upturned eyes are sometimes referred to as “cat-eyes”, and their is a clear resemblance between this eye shape and cat-eye glasses.

Close-set eyes

Rather than the shape or angle of the various parts of the eye, close-set eyes are defined by their position in relation to one another.

Eyes are generally considered to be close-set if the distance between the inner corners (from one tear duct to the other) is less than one eyeball width. Your eyes may be close set while also having a round, almond, or any other shape.

Wide-set eyes

Once again, it’s all in the name. If the distance between your eyes is greater than one eyeball width, your eyes are considered to be wide-set.

Although particularly wide-set eyes can be a trait attached to certain medical conditions, some people’s eyes are simply further apart than others.

Deep-set eyes

With deep-set eyes, the eyeball sits further back in the socket, creating the opposite of the bulging appearance associated with protruding eyes.

As the eyes are further back in the skull, the brow bone has a more prominent, even protrusive look.

Hooded eyes

Hooded eyes occur when there is an overhang of skin on the upper eyelid. This conceals the crease in the eyelid, with the excess fold of skin sometimes extending past the edge of the upper lash line, hence the name “hooded eyes”.

DID YOU KNOW?

The shape of your eyes can determine whether you are nearsighted or longsighted.

How do I find my eye shape?

Now that you’re up to speed on the different variations, you can determine your eye shape easily by observing your eyes in the mirror and taking note of their characteristics.

Look straight ahead and also from different angles. Do not attempt to open your eyes wider or flex any eye muscles to alter their shape, otherwise, you will not be able to determine your eye shape correctly.

Here is a brief run-through of the some different combinations of characteristics, and what eye shapes they indicate:

No visible eyelid crease – monolid eyes
Crease in eyelid, white visible above and below the iris – round eyes
Outer corners level with (or lower than) inner corners – downturned eyes
Flap of skin hiding the inward crease in the eyelid – hooded eyes
Top and bottom eyelids touching the iris, visible crease – almond eyes
Outer corners higher than inner corners with an upwards flick – upturned eyes
Prominent brow bone, round eyes with a lot of white visible – protruding eyes
Distance between eyes greater than the width of one eye – wide-set eyes
Distance between eyes less than the width of one eye – close-set eyes

Can eye shape affect vision?

The eye shapes detailed in this article refer to the aesthetic appearance of eyes and how they are positioned on the face. Your eye shape is a genetic trait that has an aesthetic effect on your appearance, but generally does not affect vision.

Eyeball length, on the other hand, is the cause of some common vision problems.

Myopia and hyperopia

An elongated eyeball is responsible for myopia (shortsightedness), which causes blurry distance vision. Conversely, if the eyeball is shorter than usual, it results in hyperopia (farsightedness), which blurs objects in your near field of vision.

Both conditions are refractive errors, direct results of the shape of the eyeball.

Exophthalmos

Protruding eyes can be a natural aesthetic trait caused by the position of the eyeballs in the skull.

However, if you don’t have naturally protruding eyes and you notice that they appear to be bulging, see an eye doctor immediately. Exophthalmos is a condition that causes one or both eyes to bulge, and is often an indicator of hyperthyroidism.

Ptosis

Hooded eyes are a hereditary trait, but eyelids also tend to droop with age, sometimes leading to a condition called ptosis. Ptosis occurs when the eyelid remains in a semi-closed position, or a flap of skin from the eyelid hangs over the upper lash line, obscuring vision.

If severe and left untreated, it can lead to vision problems like astigmatism or amblyopia. Ptosis can be surgically corrected, either for cosmetic reasons, or to prevent further vision obstruction or loss.

In the vast majority of cases, the natural shape of the eye does not need to be surgically altered, although some people seek cosmetic surgery to achieve their preferred aesthetic. Alternatively, some turn to makeup to achieve the same result less invasively.

Although you can’t permanently change the shape of your eyes by applying makeup, applying mascara, winged eyeliner, or a smokey eye could enhance or soften your natural features.

Choosing glasses for your eye shape

When choosing a new pair of glasses, you should always take your face shape into consideration to get the most harmonious aesthetic results.

Eye shape is less important, but there are certain frame styles that may complement your particular eye shape a little more than others.

Thin frames

Thin frames are a popular choice among most eyeglass wearers as they are featured in many different styles and colors.

Office-chic, rectangular black frames are a timeless choice, as are more rounded, golden frames with a delicate nose bridge. If you have close-set eyes, a frame with a thin bridge is a flattering option.

Bold frames

If you’re on the other end of the scale and have wide-set eyes, a chunkier frame will suit you well. Bold frames come in a range of colors— from shades of tortoise shell to transparent pink.

Bright colors with a chunkier frame can also draw attention away from the gap.

Geometric frames

Playing with geometric shapes can be a fun way to accessorize and add interest to your every-day look. Square frames create a flattering contrast to round eyes, however, round frames also suit round and protruding eyes.

For almond eyes, try to find a frame that’s similar to the eye shape itself, such as cat-eye frames.

No matter your eye shape, glasses can be used to embrace and enhance your natural features. What’s more important is to have fun with your look and choose a comfortable frame that reflects your personal style.

Confidence and comfort are key

Beauty is in the eye of the beholder, regardless of what shape it is! To really get the best results, choose a pair of glasses that you feel confident wearing and are comfortable in, even if it means going against the grain.

Although we may not be able to provide makeup tips, our optical experts are available to assist you in finding the most suitable glasses for any of your eye-care needs.
