Nearsighted Glasses
SUMMARY

Nearsighted glasses are designed to correct myopia, a refractive error that makes distant objects appear blurry.

As they have a concave “minus power”, the lenses reduce the eye’s focusing power, helping achieve clear distant vision.

There are different options for nearsighted glasses depending on prescription and lifestyle.

If you’re looking into nearsighted glasses, chances are you already know you’re nearsighted and need a pair of specs or want to learn more about the condition.

In this article, we’ll explain what nearsightedness is, what to do when suffering from it, and how to choose the best glasses. We’ll also debunk some myths and convictions on nearsightedness so you have all the correct answers to your questions.

Am I nearsighted?

Nearsightedness, technically known as myopia, occurs when you can see objects close up but have difficulty seeing objects that are far away. Suffering from myopia and not being able to see distant objects can lead to headaches, eye strain, and squinting when not seeing correctly.

To relieve these symptoms and have good vision, you must see an eye doctor and get an accurate prescription.

Nearsighted vs. farsighted

You can wear glasses for both near and far distances. While nearsightedness occurs when you’re not able to see objects that are far away, farsightedness is the opposite.

Being farsighted, or having hyperopia, means you cannot see objects at a close range. Some eye conditions entail that you might need two prescription powers for both myopia and hyperopia. In these cases, bifocal lenses or multifocal lenses are required.

What lenses correct nearsightedness

Nearsightedness is corrected with ‘minus power lenses’ that are concave-shaped and help the eye focus properly. They are called ‘minus’ lenses because they correct myopia by reducing the eye’s focusing power.

The power of lenses is measured in diopters; when having myopia, there is a minus before the diopters on the prescription provided by the eye specialist. If you’re having trouble reading your prescription, check out our quick guide or ask our online opticians for help.

DID YOU KNOW?

Nearsightedness is also sometimes called shortsightedness, and its medical name is myopia.

What are the best lenses for myopia?

Once you know how to read your prescription and understand your needs, you’ll have to choose the best lens option. Here’s some information to help you with that:

  1. Single-vision lenses correct one single visual difficulty. It can be distance, intermediate, or near vision.
  2. Bifocals combine two corrective powers: the top half clarifies objects at a distance, and the bottom half clarifies objects close up.
  3. Progressive lenses offer the same three correction powers but without the lines across the middle. The different prescriptions blend into one another seamlessly.

To help understand the difference, we’ve covered theree lenses, but it’s worth noting that at SmartBuyGlasses, we only sell single-vision and progressives lenses.

Can you wear nearsighted glasses while reading?

As previously mentioned, nearsighted glasses should help you see objects that are far away, not close up. If you struggle with reading or cannot see objects that are close up, you might also have astigmatism or hyperopia, which means you should speak with a specialist and renew your prescription.

Should I wear distance glasses all the time?

Depending on the severity of your myopia, you may only need glasses for certain activities, such as watching a movie or driving a car. Alternatively, if you are highly nearsighted, you may need to wear them all the time.

If you need more clarification about whether you should be wearing your glasses all the time or only for certain activities, consult your eye care specialist.

Can I buy nearsighted glasses over the counter and what are the best options?

Simply put, purchasing nearsighted glasses over the counter is not advised. The main reason is that nearsighted glasses require an eye care specialist prescription.

If you don’t want to waste precious time going from store to store to choose a pair of frames, the best online option to buy glasses that will correct your myopia is SmartBuyGlasses. In four easy steps, you’ll get a pair of brand-new specs delivered to your door:

Discover all that Ray-Ban has to offer: iconic frames and a spectrum of innovative lenses are waiting for you.

Please note: At SmartBuyGlasses, we pride ourselves on offering an extensive collection of Ray-Ban frames and non-prescription  lenses. However, please be informed that we do not provide prescription Ray-Ban lenses.

The Ray-Ban logo is recognized worldwide, as the brand has continuously delivered innovative eyewear solutions for almost a hundred years now.

Its iconic frames, from Aviators to Wayfarers, have become cultural symbols. But at the heart of these frames lie the lenses, designed with meticulous care and technology.

More and more people choose Ray-Ban sunglasses lenses each season.

Why? Because the brand consistently provides high quality, innovation, customization, superior performance, and comfort in all its lenses and frames.

Ray-Ban’s sunglasses range offers a wide variety of lens types, each one having its own unique characteristics and purpose.

Ray-Ban sunglasses solid lens color

As the name implies, this type of Ray-Ban sunglasses lens comes in a solid color. They are non-mirrored and non-polarized. 

Green classic G-15

Similar to the story of Ray-Ban Aviator sunglasses, the classic Ray-Ban G-15 lens was originally developed for military pilots in 1937.

It has a solid green color and operates in a range of conditions, from low-light to sunnier conditions.

These sunglasses offer a high level of clarity, comfort, protection, and more accurate vision by absorbing 85% of visible light and filtering out most blue light, as well as achieving outstanding color contrast.

Brown classic B-15

As the twin to the Ray-Ban G-15 lenses, it offers the same high performance with a high level of clarity, comfort, and protection.

However, brown lenses provide greater contrast in low-light conditions, and perform better on cloudy days.

Gradient lenses

Gradient lenses by Ray-Ban are characterized by a smooth shift from a solid color to a transparent shade of that color. Functionally, they offer varying levels of protection from sunlight.

This can be useful when light varies, such as driving during sunrise or sunset. Their gradual color transition also provides a unique aesthetic, making them versatile to suit different looks.

Thanks to the brand’s precise chemical immersion process, its plastic sunglasses lenses have a receding transition from a dark to light shade.

In contrast, high-vacuum processes leave the crystal lens tinted on the back, allowing for smooth color transitions.

Polarized lenses

Ray-Ban polarized sunglasses have lenses engineered to reduce glare from reflective surfaces, such as light bouncing off water or snow.

By filtering out scattered, reflected light, these lenses offer enhanced clarity and reduced eye strain.

They are fantastic for those who do a lot of sporting activities such as daytime fishing, skiing, mountaineering, hiking in snowy areas, or even sunny highway driving.

Chromance lenses

Among the top Ray-Ban frames and lenses is the revolutionary Ray-Ban Chromance lens, featuring innovative technology for those who love color.

Indeed, Ray-Ban Chromance technology is about enhancing color intensity and clarity. By adjusting light wavelengths, these lenses can make colors appear sharper, with enhanced contrasts.

In addition to providing a richer visual experience, Chromance lenses incorporate the benefits of polarized filters, which can be instrumental in reducing reflections and optimizing comfort.

They meet the demands of a fast-paced urban lifestyle and are perfect for challenges faced in a sporting environment and outdoor use.

DID YOU KNOW?

Ray-Ban introduced transition lenses before Transitions® did! Its trademark Ambermatic lens, launched in 1978, changed from yellow to dark brown/grey according to the weather conditions.

Mirrored lenses

Mirrored lenses come with a reflective optical coating on their outer surface. Aesthetically, this gives them a shiny, mirror-like appearance.

From a functional perspective, they reduce the amount of light that reaches the eyes. This characteristic can be beneficial in very bright conditions.

The reflective nature of these lenses also offers the wearers a degree of privacy, as onlookers are typically unable to see the wearer’s eyes.

The Ray-Ban mirrored sunglasses coating is made by fusing superheated metal oxides to the lens at a molecular level to ensure a uniform layer.

High-quality options

Ray-Ban lens innovation provides the wearer with benefits that go beyond UV protection.

From enhancing color contrasts to reducing glare, each lens type has unique characteristics catering to various visual needs and requirements.

Moreover, while we do not offer Ray-Ban prescription lenses, it’s possible to incorporate your prescription details into new prescription lenses provided by SmartBuyGlasses.

All you need is to choose your favorite Ray-Ban frame, have your prescription at hand, and follow a few easy steps.

When choosing glasses for your child, there are a lot of things to consider, from lens type and materials to the need for durability. Our guide identifies all of these factors and will help you to make the best choice possible.
5 Tips for Buying The Right Eyeglasses For Your Child

How to choose glasses for your child

Choosing the perfect pair of children’s eyeglasses frames can be a stressful ordeal. Having options is great, but when there are so many different frames and lens materials to choose from, it can be overwhelming to say the least. Not to mention, you can’t forget the importance of eye protection, long-term durability, and warranties.

To help you on your quest of finding the right kids’ prescription glasses, here are a few easy tips and things to think about when finding the perfect pair. Firstly, it is important to get a thorough eye exam from a children’s eye doctor in order to get the right prescription in the first place. This will then determine the best type of glasses for your needs.

Lens thickness

The thickness of the glasses’ lenses will depend on your child’s prescription. Stronger prescriptions need thicker lenses and weaker prescriptions can be corrected easily with thinner lenses. However, thicker lenses tend to be heavier and need to be fitted with frames that can protect them properly.

Plastic or Metal?

When it comes to frames, both plastic and metal (wire) frames are durable. In recent years, many eyewear manufacturers have begun to duplicate adult eyewear designs into children’s glasses. That means you may even be able to find a mini-version of your own pair of glasses for your little one.

Lens material

After you’ve found the perfect frames, the next step is choosing lenses. When it comes to kids’ eyeglasses frames, polycarbonate lenses are highly recommended. They are extremely durable, scratch-resistant and offer excellent optics. Not to mention, they have built in protection against harmful UV radiation and can be made for any eye prescription.

It’s wise to stay away from glass lenses as these can easily break and cause serious eye damage.

DID YOU KNOW?

Kids can be hard on glasses, so polycarbonate lenses are a very popular choice thanks to their scratch-resistance and durability.

Comfort is key

Protection and improved vision are the most important factors when choosing glasses for children. If you are going through the process of finding glasses that your child will take care of and love to wear, paying attention to comfort is key. Of course, you want your child to feel good and enjoy wearing their glasses – otherwise it will be very difficult to get them into the routine of wearing them.

Take safety and UV protection into consideration, but don’t forget to listen to your child’s opinions. After all, they will be the ones wearing the glasses every day and should feel comfortable and happy in their glasses. 

Sports eyewear

If your child has an interest in contact sports, it may be a good time to invest in a pair of kids eyeglasses for sports. Although regular polycarbonate lenses are durable enough, normal prescription glasses frames do not hold up so well when subjected to trauma. Sports goggles like this range from PROGEAR> offer that little bit of extra protection and strength while providing the same great vision as normal prescription glasses.

And there you have it! Hopefully these tips will come in handy when you’re choosing the perfect glasses for your children. At SmartBuyGlasses, we offer several of the best-selling kids’ eyeglasses brands including Bolle Kids and Shadez – and more convenient models from value brand SmartBuy Kids. Check out our full range here.

I’ve found some glasses for my child and I’m looking for some new glasses for myself. What now?

Blue light rays at a wavelength between 415nm – 455nm can damage your retinal cells, which may lead to premature eye ageing and vision problems in the future.

What to Look for When Buying Swimming Goggles

Have you ever left a swimming session with bloodshot eyes, rings around your eyes from your goggles fitting too tightly, or felt uncomfortable wearing your goggles in the sea for fear of getting saltwater in your eye because of a poor fit?

The swimming goggles you choose are crucial. Similar to prescription glasses on land, they improve your underwater vision and safeguard your eyes.

It’s crucial to understand the different types of goggles available since many work for certain uses and have a particular fit. If you are not knowledgeable on the topic, finding what you want can be overwhelming or frustrating.

If you are a competitive swimmer, you need to perform your sport at your best, without obstacles. Aside from the more serious swimmers, even if you simply use your swimming goggles leisurely in the sea or pool, you equally want no obstacles to your fun!

Top things to consider for the best swimming goggles

Ahead of choosing your swimming goggles based on the look and brand name, you should first run through a checklist of the aspects that will ensure they will work perfectly for you.

What to Look for When Buying Swimming Goggles
What to Look for When Buying Swimming Goggles
DID YOU KNOW?

Most problems people encounter with their swimmin ggoggles can be traced back to a poor or incorrect fit.

Correct fit

The fit is one of the most important aspects when shopping for your new goggles. Even if they’re a  great-looking pair of swimming goggles, they’ll have no use if they leak water into your eyes because they are the wrong size. Contrary to the belief that the strap determines the size, it’s actually the seal on the goggles.

Thankfully, you can shop with confidence with SmartBuyGlasses, knowing we offer a 100-day returns policy. So, if your goggles aren’t perfect, you can send them back to us and choose another pair! 

Comfort

Many goggles include adjustable nosepieces, but if you adjust and they’re still excessively tight or press on the bridge of your nose, you may need to opt for a different pair.

While your swimming goggles may fit snugly over your eyes, a lack of comfort over your nose can be quite uncomfortable. As noted previously, the strap has little to do with the seal around your eyes and the water flowing in.

Excessively tight goggles will put pressure on the areas around the eyes, making swimming with them an unpleasant experience.

Split straps are now common on goggles, and they hold them in place better than a single strap. Split straps are convenient if you plan on swimming fast or turning quickly in the water.

Size

When it comes to the size of the gasket (lenses), the smaller the better to have less resistance in the water. However, they must also be comfortable, so don’t get too caught up in this. After all, there is no use in having less resistance in the water if you are slower because your field of vision is not clear.

You should also consider how they sit on your face and any possible nuisances. People experience an issue with swimming goggles: their eyelashes brushing against the lenses or the strap hurts their head. If you prefer going the distance rather than just a quick swim, minor nuisances may turn into big ones.

Do they fog?

Anti-fog and UV protection are now standard on nearly all goggles. If this is not the case, they should come at a much more affordable price. A thin anti-fog coating on the inside of the lense of good goggles should not be disturbed.

This coating should stay for a while. However, they typically lose their anti-fog characteristics over time, but luckily there are other ways to keep them fog-free!

How to keep swim goggles from fogging

If your swimming goggles fog up, you can invest in an anti-fog spray made for swimming goggles, similar to what you may see for glasses. As a last resort, you can also spit into them or lick the insides with your tongue before putting them on your eyes. Yes, it sounds strange, but it is a genuine tip to avoid fogging. 

How to properly fit swim goggles

For a proper fit, your goggles should sit comfortably on the bridge of your nose and create a seal around your eyes without any gaps.

Testing the correct fit

  • Test the seals: Gently push the eyepieces of the goggles onto your face without the strap around your head. They’re an excellent fit if they have enough suction to stick to your face for 3 to 4 seconds. Look for a smaller size if they pop off.
  • Check the nose bridge: Make sure it sits comfortably on your nose without excessive pressure or squeezing. 
  • Try different shapes: The majority of goggles have oval lenses, but some people don’t find them to be a good fit and opt for another style. Play around until you find ones that you feel good in.

There can be more things to take into consideration when buying glasses for children as opposed to buying them for yourself. This article covers all the essentials in that regard.
What Do You Need in Order to Buy Kids’ Glasses

When buying kids eyewear it is especially important that you choose the best possible design and quality in order to assure optimal eye health and comfort to your child.

However, buying glasses online can always feel a little like a lottery, you haven’t tried them on so you aren’t sure if they will fit or suit your face shape, and without holding them in your hands you can’t get a feel for their weight or robustness.

For this reason, we have put together a series of tips that you will need to take into consideration when buying your kids glasses online, to ensure that you get the best glasses for your child. 

Before buying kids glasses you should keep the following info in mind:

How should glasses fit on a child?

A child’s glasses frame should fit right into the eye socket from top to button and shouldn’t expand down the kid’s cheek. If a child is wearing a frame like this, it will cause unnecessary weight on the nose. 

However, it’s no secret that children are growing. In relation to buying kids glasses and fitting glasses, this means that there may be a problem with kids glasses frames sliding down their noses. This can cause exasperation and discomfort for your child.

The solution to this is to either buy kids glasses with metal frames and adjustable nose pads, or plastic kids glasses frames with specifically molded bridge parts.

Plastic has always been the traditional option as it is viewed as more durable and less expensive.

However, modern metal children glasses frames now offer similar levels of resistance for comparable prices, as well as the extra feature of offering cable temples (which essentially hook over the back of your child’s ear), which are sturdier and reduce the chances of kids glasses sliding or falling off.

The PD or Pupillary Distance

The PD is the distance between the centre of each pupil. It’s crucial when fitting glasses correctly as it affects the way your child’s glasses lenses are positioned in their frames, and so will impact the accuracy of your child’s vision correction.

In some extreme cases, not having the correct PD measurement can result in dizziness, headaches, and blurred vision.

All opticians measure this distance so it will most likely be noted on your child’s prescription. If it is not however, then you can either, revisit the optician and ask him to take the measurement for you, or read our article on how to measure the pupillary distance.

What Do You Need in Order to Buy Kids’ Glasses
What Do You Need in Order to Buy Kids’ Glasses
DID YOU KNOW?

In 2019, 25.3% of children aged 2–17 years wore glasses or contact lenses.

Lens thickness & materials

The thickness of the lens is dictated by the strength of your child’s prescription glasses. The higher the prescription (ie. the more vision correction needed), then the thicker the lenses will be. Your optician is best placed to advise you on the optimum lens thickness for your child’s prescription glasses.

Be aware that due to recent advances in technology, many lens makers can now “slim down” lenses that once needed to be very thick.

The material of the lens should also be carefully considered. Traditional glass lenses have now given way in the most part to high quality plastic and polycarbonate lenses. Whilst you can still buy glass lenses, they are not advisable for children’s glasses due to obvious safety reasons, as well as being a much heavier material.

For children, Trivex and polycarbonate lenses are usually recommended as they are lighter than plastic or glass lenses, and much more durable and impact-resistant. This allows for longer lasting comfort. So when buying kids glasses online always make sure you know the material of the lens you are purchasing.

Warranties

Many online optical retailers have warranty plans in place that cover damaged or broken eyewear at little to no cost. If your child is very young, or a first time glasses wearer, it’s recommended that you look into the warranty plans of each provider before you decide to buy.

Check that it includes all the services you are looking for, e.g. lens replacement or free scratch repair. It could save you a lot of money in the future.

Spring hinges

A lifesaver for those whose children are slightly more “rough and tumble”. Spring hinges are glasses whose temples are fitted with springs at the hinges in order to provide more flexibility when the temple is moved back and forth.

They increase resistance and durability and minimize expensive temple repair costs. They ensure flexibility in the arms of the glasses and don’t snap and break as easily as regular hinges. 

Back up pairs

There is always the possibility that the worst happens and your child’s glasses break beyond repair (even beyond a “scotch tape and string” job). Therefore it’s highly recommended to have a pair of back-up kids glasses that are stored away and used only when necessary.

Many optical companies offer great value with their in house brands, which means that an extra pair of glasses doesn’t have to be an expensive option. SmartBuyGlasses has a wide range of low priced, quality frames in their SmartBuy collection.

Presbyopia is a common condition that causes blurry close-range vision. Learn what it is, what causes it, and how to treat it.

If you’re thinking that your vision just isn’t what it used to be, you’re probably right. As you age, you may find that you’re struggling with things you’ve never had issues with like reading fine print.

This is normal, and completely expected due to something called presbyopia.

Presbyopia is a very common eye condition. In fact, everyone above the age of 45 is expected to experience it as it consists in an age-related loss of near vision that can be easily corrected with eyeglasses, contact lenses or surgical options.

What is presbyopia?

Presbyopia is a vision condition that causes blurred close-range vision. This is because as you grow older, your lens in your eyes lose their natural ability to focus on nearby objects. 

As this worsens and the eye struggles more and more with near vision, the presbyopia will make it harder for you to see clearly when performing certain activities such as reading, writing or looking at a computer screen.

As you age, you may notice both a loss in visual acuity (clarity) when looking at objects at close range, and blurred vision when trying to read fine print. This can be a good indicator of presbyopia, though first symptoms are not always immediately noticeable.

Presbyopia symptoms include:

  • Squinting, especially when looking at close-range objects.
  • Blurred vision.
  • Difficulties reading small print.
  • Headache and eye strain after reading.
  • Reduced focusing ability, leading to the need to hold reading material by holding at arm’s length.
  • Needing brighter conditions to read or work in.
  • Eye fatigue.

If you are experiencing any of these symptoms, you should ask your eye doctor for a comprehensive eye exam. That said, it’s best to get an eye screening around age 40, regardless of if you have symptoms. 

This is because presbyopia tends to manifest around that age, with anyone above age 40 being at risk.

Given the age-related nature of the condition, regular eye examinations can help stay on top of it by identifying vision change and any signs of sight impairment early on.

Symptoms similar to those of presbyopia can also occur in young people, though they are more often caused by eye fatigue from digital screens. That said, there’s no way of excluding vision impairments without a screening. 

That’s why it’s best to keep an eye out for these symptoms and consult your optician if you notice any changes in your eye health whatsoever, regardless of age.

DID YOU KNOW?

Presbyopia has been around for ages! The name comes from Modern Latin and finds its roots in the ancient Greek terms presbus (old man) and ōps (eye).

What causes presbyopia?

Your eye uses a natural crystalline lens to focus light on your cornea, enabling you to see. This is similar to how cameras use a lens to focus light on the film and capture an image. 

Just as the camera lens changes size when you zoom in and out of the picture, your eye’s lens is also somewhat flexible. The muscles surrounding it contract and relax as you focus, allowing it to change shape and serve as your eye’s autofocus system.

Though this mechanism tends to work very well when you’re young, your lens gets thicker as you age. This makes it much less flexible, which in turn causes the autofocus system to stop working when looking at close range items. 

Presbyopia is the medical term for an age-related decrease in near vision as a result of lens rigidity.

Unlike other vision conditions like myopia and astigmatism, it isn’t born of a defect in the eye’s anatomy but is instead an unavoidable consequence of getting older.

Presbyopia treatment

Researchers aren’t sure why the eye loses flexibility as we age, but it happens to everyone. Though it may be frustrating, it’s nothing more than an unfortunate side effect of aging that can be easily corrected through treatment options. 

Common treatments include glasses, contact lenses, medication and refractive surgery, giving you plenty of options to manage your presbyopia.

Glasses for presbyopia

Eyeglasses are the most common treatment options for presbyopia. As your eye’s natural lens loses flexibility, glasses can correct this by providing external support that allows your eyes to focus on near distances.

Reading glasses are often the best option if presbyopia is the only vision condition present.These help eyes focus when performing close range tasks, like reading a book or computer screen.

Instead, progressive addition lenses (PALs) are used when treating presbyopia in people with multiple vision conditions. Thanks to the different vision areas on the lenses, they can be fit with more than one prescription.

This allows you to correct both near vision, intermediate vision, and distance vision with a single pair of glasses.

Contact lenses for presbyopia

Contact lenses are an alternative to glasses for treating presbyopia symptoms. These can be either monovision, bifocal or multifocal contact lenses. 

Just as was the case with glasses, bifocal and multifocal contact lenses are fit with multiple prescriptions and cater to both near and distance vision correction.

Monovision contact lenses are instead lenses fit for distance vision in one lens, and near vision in the other. You can also get modified monovision contact lenses where one eye uses a multifocal contact lens and the other one uses a distance vision lens.

They are an effective solution, though they can take some time to get used to as they require switching between one eye and the other to see different distances.

Whether it’s best to wear glasses or contact lenses depends on your individual lifestyle and needs. An optician can help you understand what’s best for you. 

Medication for presbyopia

Though traditionally there was no medication available for presbyopia, the FDA has recently approved the use of pilocarpine hydrochloride ophthalmic solution as a viable treatment option.

This consists of prescription eye drops that reduce the size of your pupils, helping your eyes focus on closer objects. They are effective for up to six hours and need to be used on a daily basis.

Surgery for presbyopia

Corrective surgery is also an option for presbyopia symptoms.

Monovision LASIK surgery is a form of surgical correction used to create an effect similar to monovision contact lenses. This is achieved by correcting one eye for near vision and the other eye for distance vision.

Then there’s PresbyLASIK, a new form of corrective laser surgery developed specifically for presbyopia that is now undergoing clinical trials in the U.S.

This procedure uses a special laser (called an excimer laser) to help regain vision at multiple distances. It does this by creating a multifocal ablation pattern directly on the eye’s clear front surface.

Alongside this, other experimental treatments such as corneal inlays are being developed and tested. One promising study focuses on injecting an elastic gel into the structure in the eye that contains the natural lens (called the capsular bag).

This is a more permanent treatment that could potentially offer a significant improvement in visual function.

In theory, the gel could replace the natural lens and serve as a new, more elastic one. In addition, some people undergoing cataract surgery may be able to achieve clear vision across all ranges by choosing presbyopia-correcting intraocular lens.

Your vision is expected to worsen as you get older, and that’s okay. Presbyopia is a frustrating part of the aging process, but it can easily be corrected by staying on top of it.

Remember, it’s important to get the recommended vision screenings as an optician will be able to check for early signs of vision conditions and adjust your prescription as needed. 

And if you still have doubts about glasses and contacts for presbyopia? Don’t worry about it, feel free to ask our opticians anything. They’re here to help you see more clearly!

How To Do An Eye Test Online

Eye test online: key information | Who can take an eye test online? | Eye test for astigmatism online | How to take online eye test for glasses | SmartBuyGlasses lens scanner | Technologies at SmartBuyGlasses

Eye tests are now available online,. They can't tell you as much as an in-person eye test at your eye doctor, but they can provide some useful information.
How to Do an Eye Test Online

In 2020, completing normal tasks from home has become the norm. Getting an eye test online, for example, is just one of the numerous socially-distanced options for getting stuff done without going out.

Want to test your eyesight without a trip to the optician? Online vision tests are a pretty good way to make that possible.

An online eye test might check:

  • How sharp your vision is.
  • Whether you have astigmatism, a condition that can make things blurry or stretched.
  • How sensitive your eyes are to light.
  • If you have color blindness, meaning you can’t see colors correctly.

These eye tests can be helpful in some situations, like if you break or lose your glasses when you’re far from home and you need a prescription to get new ones.

Importantly, they cannot replace regular visits to your eye doctor. That’s because they are only about vision; obviously, they cannot check the health of your eyes. An online-only eye test can’t tell you if you have a condition that can seriously threaten your sight, like cataractsglaucoma, or macular degeneration.

If you think you have an infection or you’ve injured your eyes, you should see an eye doctor as soon as possible.

Who can take an eye test online?

Online vision tests are best for healthy adults aged 18-39 who:

  • Already have a prescription for eyeglasses and it’s not very strong.
  • Have already had a complete eye exam and know their eyes are healthy.
  • Have no risks for eye disease, like diabetes or high blood pressure.

Even if you are the right age and healthy enough to take an online vision test, you should still get regular in-person eye exams as often as your eye doctor recommends.

At SmartBuyGlasses, we’ve prepared this really handy eye test to help you work out whether you’ve got astigmatism. Simply follow the link here to take the test.

How to take online eye test for glasses

It should be noted that online-only eye tests can never be fully accurate; it’s always best to visit an eye doctor. However, in the current climate, it may be a good idea to get a general idea of what your eyesight’s like before you go and see an optician.

DID YOU KNOW?

Although useful, online eye tests cannot check the physical health of your eyes, and so cannot detect conditions such as cataracts and macular degeneration.

Arise Collective™ Clarity prescription lenses are advanced, affordable prescription lenses from Arise Collective™ sold exclusively at SmartBuyGlasses. The Arise Collective™ Clarity lens collection comes packed with protective elements to provide you with an unbeatable pair of prescription glasses.

From scratch resistant and anti-reflective coatings to UV 400 and superhydrophobic protection – these lenses are purpose-built to protect your eyes, no matter the conditions.

These lenses are also aspheric, making them thinner and lighter than many other prescription lenses. These high performing, durable lenses feature an innovative lens technology that provides optimal clarity and comfort from the urban jungle to the actual jungle.

Blue light glasses

Blue light glasses technology from zFORT® is another future-proof feature present in a whole range of products at SmartBuyGlasses. Blue light is a potentially harmful, high energy visible light which comes from the sun – but, importantly, is also emitted by electronic devices.

With our increasing reliance on such devices, our exposure to blue light has never been higher.

Energy at a wavelength between 415nm and 455nm, is ‘blue light’. It can hit the retina and have a detrimental effect on vision that may lead to premature eye ageing. Our exposure to this potentially harmful form of light may also cause a whole range of other health problems.

It’s important that you protect yourself every step of the way with some blue light blocking glasses.

Color Blind Test - Online Self Test

You may have heard of color blindness but not really know exactly what it means. Find out everything you need to know about the causes, symptoms, tests and treatment for color blindness.

What is color blindness?

Color blindness is a term for when someone is unable to see colors in a normal way. More accurately, it is a color deficiency rather than color blindness. Often, someone may not be able to distinguish between certain colors, most commonly between reds and greens and occasionally blues.

What causes color blindness?

In the retina of the eye, there are two types of cells, rods and cones, that detect light. Rods detect light and dark whereas cone cells detect color. Cone cells are concentrated in the central area of the retina in the macula. There are blue, green and red cones and your brain uses input from these cone cells to determine your color perception.

Color blindness can occur when there is an abnormality in these color cone cells. This could either be because there is an absence of cone cells, some of them may not be working correctly or some may detect a different color than normal.

You usually suffer with color blindness from birth and generally males are more affected than females. However, you can also acquire it later in life as a result of trauma, diseases including metabolic and vascular diseases, toxic effects from drugs and general aging.

If you experience a significant change in color perception, you should visit an eye specialist.

Types of color blindness

Severe color blindness occurs when all three cone cells are absent, and this is known as achromatopsia.  In this case, you will see everything in different shades of gray! Mild color blindness is when one cone cell does not work properly, and you may see colors normally in good light but struggle in dim light.

Color blind symptoms

Symptoms can be so mild that you may not even realize that you have a color deficiency! However, they can also be severe and include:

  • Difficulty seeing colors and the brightness of colors
  • Difficulty or inability to tell the difference between shades of the same or similar colors
DID YOU KNOW?

Red-green color blindness is the most common type of color blindness. As the name suggests,it makes it hard to tell the difference between red and green.

Is there a color blind test I can take?

You can very easily do a color blind test online without having to go to an eye specialist. This test, also known as the Ishihara test, is a fast and simple way to determine whether you struggle to perceive color in a normal way.

The test is made of a series of ‘plates’ of colored dots. In the center, the colored dots make up a number, and this number is surrounded by colored dots of a different color.  

Have a go! See the answers at the end of the article.

  1. Firstly, make sure you have the lights on. If you wear glasses of contact lenses, you can wear them to do the test.
  2. Look at the patterns made up of multi-colored dots.
  3. If you can make out the numbers and shapes among the dots, you do not have a color deficiency.
  4. If you struggle to do this, you may have a color deficiency and it is advised that you visit an eye specialist for a more comprehensive test.

If you are not sure about this test or if you would like more accurate results, visit an eye specialist to take a color blind test administered by a trained professional using standardized testing materials under proper lighting.

For a color blind test for kids, it is advised that you book an appointment with an eye specialist.

Is there a treatment for color blindness?

There is no treatment for inherited color blindness but there are special contact lenses and glasses that may help to enhance color perception.

If you have acquired color blindness, an eye specialist may be able to address the underlying condition that caused the problem.

If your eye specialist recommends that you wear eyeglasses or contact lenses, SmartBuyGlasses has you covered!

You can also check the current prescription of your eyeglasses using SmartBuyGlasses’s revolutionary Lens Scanner app. In just a few easy steps, you can extract your current prescription using just the app, your eyeglasses, a screen and a magnetic card. Do it from the comfort of your own home in a matter of minutes!

Everything You Need to Know About Multifocal Contact Lenses

The world of multifocal contact lenses can be rather overwhelming –  and that’s an understatement!

But fear not; you are in the perfect place to find out everything you need to know. Get ready for the simplest possible breakdown of multifocals.

What are multifocal contact lenses?

Multifocal contact lenses are a type of lens that can correct vision for individuals who suffer from both presbyopia and other refractive errors.

These lenses work by combining prescriptions for distance and up-close vision into a single lens. They offer an alternative to wearing glasses, which may not always be practical or desirable.

With multifocal contact lenses, wearers can enjoy improved vision for both near and far distances, without having to switch between multiple lenses. 

There are different ways to achieve multifocal lenses. some will provide the distance and near in the one lens. Others will have the ADD power in both, but one eye is for seeing near and the other for seeing further away.

Finally there are some that have one eye strictly for near and the other only for for distance.

How do multifocal contact lenses work?

For people who wear contact lenses, having to switch between multiple pairs for different settings can be inconvenient.

Fortunately, multifocal contact lenses solve this problem by allowing wearers to see clearly at different distances with just one pair of lenses.

This allows for a smoother transition between different environments, such as going from reading a book to driving a car.

Multifocal or varifocal contact lenses are a great option for those who want convenience and ease of use while still maintaining clear vision.

Its important to note that this transition may not always be perfect and may take some getting used to. This is an important factor to discuss with your optometrist when getting fitted.

Aspheric vs concentric - which multifocal lenses are right for me?

It is important to note that there are two types of multifocal lenses available, aspheric and concentric.

Concentric ring design

Concentric circles vary in diameter, but share the same center. Concentric ring design involves a central circular prescription lens, and alternating concentric circles surrounding the central point.

The eye then alternates between the rings to see at different distances with a gradual transition.

There can be multiple layers of rings, two of which are usually within the pupil’s range. This range varies as the pupil contracts and dilutes according to the levels of light.

Concentric ring lenses are available in both soft and hard gas permeable materials. However, the location of the prescription will vary according to the material.

A hard or rigid gas-permeable lens features the long-distance prescription in the central point of the lens.This is referred to as the center-distance. 

A soft contact lens will comparatively place the short-sighted prescription in the center of the lens. In this case, the prescription is known as the center-near.

It is also possible to have a central near-sighted prescription in the dominant eye, and a long-sighted center for its non-dominant counterpart.

DID YOU KNOW?

Varifocal contact lenses work by combining multiple prescriptions in each lens, allowing the wearer to see clearly at both near and far distances without having to switch lenses. 

Aspheric design

Aspheric design in multifocal contacts is similar to progressive lenses in glasses, where the various prescriptions merge across a single lens.

Aspheric lenses are designed to be flatter and smoother than traditional spherical lenses, which can result in sharper and clearer vision for wearers.

Additionally, they can provide a more comfortable and natural fit, reducing the chances of irritation or discomfort. 

Aspheric lenses are particularly beneficial for those with higher prescriptions or astigmatism, as they can reduce visual distortions and improve visual acuity. 

Are multifocal contact lenses right for me?

Before knowing if any contact lenses suit your needs, speak to your optician to determine if they’re a good option.

Its essential to note that not everyone can wear them, so an eyecare specialist is a good place to start before finding out the basics of how they will work when you wear them. 

Multifocal or varifocal contact lenses as a standalone product are designed with a gradual transition between a prescription for close reading on one end and a prescription for normal distance viewing on the other.

They are very similar to progressive eyeglasses.The human vision system learns to select the appropriate prescription through the lens, depending on the desired distance at the time.

As mentioned, here are two ways that multifocal contact lenses are designed: concentric ring design, and aspheric design.

Multifocal contact lenses come in both soft lens and rigid gas permeable (RGP, or hard) lens materials.

How to use multifocal contact lenses

Wearing multifocal contact lenses can be a daunting task, but with proper insertion, there is nothing to worry about.

To use multifocal contacts, it’s important to follow the instructions provided by your eye doctor and the manufacturer. 

These may include proper cleaning techniques and a specific wearing schedule.

With some practice and patience, wearing multifocal contacts can become second nature and provide clear vision for all of life’s activities.

Choosing multifocal contact lenses: advantages and disadvantages

Multifocal contact lenses are not suitable for everyone. Read on to find out the advantages and disadvantages of using them.

Advantages

You will no doubt be pleased to hear that multifocal contact lenses are available for various usage periods e.g. reusable multifocal contact lenses, or daily or monthly multifocal contact lenses.

There are also options between soft and rigid designs to suit your personal preference. A key benefit is that you can get multifocal contact lenses for astigmatism.

This is a type of refractive error, meaning that the eye does not focus light evenly on the retina, resulting in blurred near and distance vision.

Those with astigmatism would often also develop presbyopia around the age of 40. 

This led to a tricky decision: opt for wearing reading glasses on top of contact lenses or wear bifocal glasses. Thanks to multifocal lenses, clear, seamless vision is now achievable with much less compromise.

advantages and disadvantages of contact lenses

Disadvantages

There are some disadvantages to multifocals that may mean they are not the right lens for you. Often there is hazy or shadowed vision early on in the adjustment process.

Multifocal contact lenses come at a higher cost compared to standard contacts. This is owing to the more complex prescriptions and precision required when fitting them. 

The cost of varifocal lenses is an important factor in deciding your method of vision correction but ultimately it should be something that you speak with your doctor about.
