Sunglasses work mainly as protective items and only secondly as decorations. There are however people who cannot buy a pair of sunglasses and enjoy them because they have special eye conditions. Hyperopia, myopia and astigmatism are just a few examples here. Prescription sunglasses could be a solution for improving sight and protecting eyes from the action of the UV radiation at the same time. The UVB rays cause sunburn while the UVA rays get absorbed by the human eye lens.
Prescription sunglasses represent a combination of regular glasses with a dark lens design. There are different kinds of lenses used for prescription sunglasses, and here we can count polarized lenses, anti-reflective lenses, blue blockers, photochromic lenses and gradient lenses. It is important to mention here, before going on with the description of prescription sunglasses, that you can only order this kind of eyewear based on an ophthalmologist’s recommendation and after careful medical examination. Some health condition such as eye surgery may require total prevention of sun exposure. This is why most often doctors prescribe sunglasses with 99 or 100% protection against UVA and UVB.
Wraparound designs could be a good solution for prescription sunglasses as you’ll also be protected at the sides of the eyes too. The frame makes such protection possible, because a too thin or small frame design will be insufficient. As for the glare, all quality sunglasses should incorporated the polarized coating for a superior protection of the eyes. Mirror-coated lenses are sometimes used for the same purpose of reducing glare. The stage of the eye condition will also have an influence on the design of the prescription sunglasses.
It is sometimes difficult to create functional prescription sunglasses for advanced forms of myopia where the thickness of the lenses is very high. There are other situations when two or more health problems are present, as one person could suffer from both astigmatism and myopia, to give just an example. Solutions may be available, but only a specialist will be able to tell you which is the best for you. Very few companies can provide such designs for low prices; the more complex the prescription sunglasses, the higher the price.
