Sunglasses are widely worn by different class of ages, even the best fashion brands have their own sunglasses colletions… Why prescription sunglasses?
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. 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. The UVB rays cause sunburn while the UVA rays get absorbed by the human eye lens.
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. 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.
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. 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. 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. Very few companies can provide such designs for low prices; the more complex the prescription sunglasses, the higher the price.
