Nose bridge - The part of the glasses frame that sits on your nose, connecting the two lenses. A well-fitting nose bridge distributes the weight of the glasses evenly, ensuring comfort and stability. Different styles of nose bridges are available to accommodate various nose shapes and sizes.

Night vision glasses - Glasses designed to improve visibility in low-light conditions, such as during nighttime driving. These glasses often feature anti-reflective coatings and yellow-tinted lenses to reduce glare from headlights and streetlights, enhancing contrast and making it easier to see in the dark.

Myopia - Also known as nearsightedness, a vision condition where close objects are seen clearly, but distant objects appear blurred. Myopia occurs when light focuses in front of the retina instead of directly on it, usually because the eyeball is too long. Glasses or contact lenses with negative diopter values (minus lenses) are used to correct this refractive error.

Macular degeneration - Age-related Macular degeneration is a condition that affects the macula, the central part of the retina responsible for sharp, detailed vision. Macular degeneration leads to the gradual loss of central vision, making it difficult to read, recognize faces, or see fine details. While there's no cure, treatments can slow its progression.

Lazy eye (Amblyopia) - Also called a lazy eye, this is a disorder of sight in which the brain fails to fully process vision from one eye, over time the brain will ignore this eye and will favor the other eye. This can result in poor depth perception and visual clarity. Early diagnosis and treatment, such as corrective glasses, eye patches, or exercises, are essential to improve vision in the affected eye,this needs to be achieved before the age of 7.
