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. 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.

Dark lens design and prescription lens structure represent a medical solution to create a product of sun protection eyewear type. Prescription sunglasses use different types of lenses, 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.

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. 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.

Prescription sunglasses can provide the needs of people who have eye problems but are keen to explore the outdoors during bright.
