Clutches for Less

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. 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.

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, all quality sunglasses should incorporated the polarized coating for a superior protection of the eyes. 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.

For instance, people who suffer from advanced myopia may require very thick lenses, which could be incompatible with most of the frames. 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.
