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. 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. 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. 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. 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. 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. Very few companies can provide such designs for low prices; the more complex the prescription sunglasses, the higher the price.
