Prescription Sunglasses – Worth The Money?
Friday, March 12th, 2010Sunglasses 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. 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. Prescription sunglasses use different types of lenses, 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. 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, 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. 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. 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. Moreover, price awareness is another important element given the fact that prescription sunglasses will always be more expensive, as the number of specialists who can design them is smaller too.
