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. This is the case with anyone who suffers from myopia, astigmatism or hyperopia. 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.
Dark lens design and prescription lens structure represent a medical solution to create a product of sun protection eyewear type. There are different kinds of lenses used for prescription sunglasses, such as gradient lenses, anti-reflective lenses, blue blockers, polarized lenses and photochromic 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. Total protection against the UVAs and the UVBs should be covered at optimal parameters, due to the fact that people with eye surgery should not be exposed to powerful radiation.
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, not only prescription sunglasses but most sunglasses in general have a special anti-reflective coating that ensures superior reflexion of the light. The amount of light that enters the eyes could also be limited by using mirror-coated lenses. One special mention here is that the design of the prescription glasses also depends on the stage of the eye health condition.
It is sometimes difficult to create functional prescription sunglasses for advanced forms of myopia where the thickness of the lenses is very high. The presence of two or more health problems at the same time could also become an obstacle for the design of prescription sunglasses. The doctor should be able to recommend an adequate course of action, with the mention that the design of highly specialized prescription sunglasses is more difficult. Very few companies can provide such designs for low prices; the more complex the prescription sunglasses, the higher the price.
