Homo Sapiens belong to the species where comfort is accorded a high status. Comfort leads to style to express a level of individuality which then becomes fashion. The term fashionable then crosses the boundary to over the top styling where comfort takes a back seat. The cycle gets repeated and soon comfort leads to the same style. Nowhere is this truism more apparent than in eyewear.
Eyewear fashion such as sunglasses is cyclic in nature. What is fashionable a few years back becomes the new style as the packaging and glitz accompanying it make it seem like new fashion. This does not purport that all fashion in sunglasses are recycled. Only some as creative instincts of Man can think and execute something not seen before.
Sunglasses started as a result of avoiding the harmful effects of UV reflection from the snow. The function has evolved into form and style that has taken the world by storm. Riding the boom in sunglasses marketing is America’s premier wholesale sunglasses enterprise ctswholesalesunglasses. There is not a style of sunglasses this company does not distribute. They have the expertise of sourcing from some of the best and the largest for example from Xiamen in China.
Sunglasses are manufactured with polarized lenses. Apart from stylish appearance sunglasses can add visual comfort and clarity in protecting the eyes from harsh effects of glare from sunlight. Polarized lenses reduce glare; Glare is caused when sunlight reflects off the shiny road surfaces.
A major benefit of wearing sunglasses are protection against too much exposure of light, such as ultraviolet radiation (UV). This can cause problems in ocular vision such as
- Snow blindness
- Variants of cancer of the eye
Sunglasses can filter almost 99% of UVA light up to 400 nanometers. People who wear spectacles can also get the benefit of protection from UV by wearing overglass sunglasses. These are polarized lenses that clip on the existing frame of the spectacles. The wearer is not hampered for distant vision while at the same time the reflection of UV radiation is filtered out.
It is important that lenses manufactured for sunglasses follow the general classification or standards. Earlier many claims by manufacturers that the lens would meet the prescribed standard has been found deficient as opticians having the necessary equipment to measure the refractive index were able to disprove the claim. Other precaution in wearing sunglasses is the fit where the lens should fit the face and eyes properly allowing minimum stray light to reach the eye.
