June 8th, 2010 by Edward Turner Leave a reply »

Contemporary sunglasses can take use of colored and polarized lenses so that they are now available in different types. It is a fact that sunwear models coming with colorful frames and lenses look probably quite charming and attractive. For young ladies, sunglasses in green, blue or purple can be a great lure. And the fashion sunwear industry has mainly occupied by those colored sunglasses. This reflects people’s natural pursuit for a better look with eyewear, provided enough UV protection is ensured. Even if colored sunglass lenses are gaining popularity, it is still able to see many people who choose to wear dark sunglasses, which is the original form of sunwear. These primary sunglasses take use of dark lenses. Of course, these darkened lenses are capable of filtering out unwanted UV rays and blue light. Human eyes can receive more light than usual during outdoor activities but excessive exposure to ultraviolent light will damage the eyes and even cause certain eye diseases.

Dark sunglasses can always do a good job in providing adequate UV protection. It is for sure that such a protection is invisible. And dark lenses do not automatically block more harmful UV light than light lenses. The key point of guaranteeing the protection is to make dark lenses sufficiently protective. Or it is equal to say that these lenses should be adequately dark. Inadequate dark lenses provoke the eyes to open wider and more unfiltered rays will enter the eyes. Another point is that lens color does not determine the degree of UV protection. In this case, dark sunwear can actually be as competent as lenses of various colors. And expensive brands providing dark models do not guarantee optimal UV protection.

As a basic sort of sunwear, dark sunglasses maintain a stable group of users due to its natural features. Compared with colored sunglasses, dark models seem more normal and prudent. So, it is not surprising that many policemen choose to wear dark glasses, rather than a green or blue pair. Dark sunwear still has a particular function. Many celebrities such as movie stars use dark glasses to mask their identity in public.
