A Positive Guide to Prescription Sunglasses
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.
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. 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.
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. 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. 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.
