How To Find the Right Prescription Sunglasses

March 13th, 2010 Posted in Outdoors

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. 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. 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. Here, the choice of the frame is everything because it should be large enough to allow for such protection. 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. 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.
