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. 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.
Prescription sunglasses represent a combination of regular glasses with a dark lens design. There are different kinds of lenses used for prescription sunglasses, such as gradient lenses, anti-reflective lenses, blue blockers, polarized lenses and photochromic lenses. Prescription sunglasses are designed only according to the ophthalmologist’s recommendations, and sometimes design is not possible because of the specificity of the eye problems. 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. 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. 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. 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. 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.
