Although very often we tend to consider eyewear as a form of decoration, sunglasses are first and foremost a protection of the delicate eye system from the impact of the ultraviolets. 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. 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. The UVB rays cause sunburn while the UVA rays get absorbed by the human eye lens.

Prescription sunglasses represent a combination of regular glasses with a dark lens design. Prescription sunglasses use different types of lenses, and here we can count polarized lenses, anti-reflective lenses, blue blockers, photochromic lenses and gradient 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 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. One special mention here is that the design of the prescription glasses also depends on the stage of the eye health condition.

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.
