the enemies of vision
There are various lens protection technologies available for prescription and non-prescription eyewear.
Glare resistant -
A set of ultra- thin layers on the lens surfaces that eliminates reflections to dramatically reduce glare. Reflections on both sides of the lens can lead to the wearer experiencing glare, which creates visual discomfort and reduces clarity of vision. An anti-reflective lens also gives better vision for night driving, which means improved safety – and for computer use, which means less eyestrain
. As the lenses are more transparent, the wearers eye are no longer hidden behind reflections.
Scratch-resistant technology -
A hard film that creates a much tougher surface on lenses. (These are still susceptible to damage, especially if dropped). The technology gives glasses a longer life and protects visual clarity. This is a must have, and even more so on children’s glasses.
Water Resistant -
A water resistant treatment that repels water droplets, preserving clarity of vision. Lenses with a water-repellent surface prevents water collecting. The water rolls into small droplets and slides off the lens with ease. With ordinary lenses water spreads and sticks to the surface.
UV Protection -
A clear filter on the lenses that protects the eyes from damaging UV light, which can be applied to glasses as well as sunglasses. UV light is harmful to eyes, and has been linked to the development of cataracts
and eye cancer. People who regularly spend time outdoors should opt for UV protection. UV protection is recommended for all sunglasses but can also be applied to clear, everyday lenses too.
