Sunglasses work mainly as protective items and only secondly as decorations. Special vision problems prevent lots of people from being able to wear sunglasses, which makes them even more exposed to various other eye health problems. Hyperopia, myopia and astigmatism are just a few examples here. The solution for such cases is to be found in prescription sunglasses designed to match exactly the same features of the regular glasses but with ultraviolet protection. On the one hand the UVA rays get absorbed in the body through the eye lens, and on the other, the UVB rays cause skin burn.

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.

Some prescription sunglasses rely on a wraparound design that prevents the UV rays from entering from the sides. Here, the choice of the frame is everything because it should be large enough to allow for such protection. As for the anti-reflective properties, all quality sunglasses should incorporated the polarized coating for a superior protection of the eyes. The amount of light that enters the eyes could also be limited by using mirror-coated lenses. The stage of the eye condition will also have an influence on the design of the prescription sunglasses.

For instance, people who suffer from advanced myopia may require very thick lenses, which could be incompatible with most of the frames. The presence of two or more health problems at the same time could also become an obstacle for the design of prescription sunglasses. 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.
