Sunglasses have become a true fashion accessory for most of us. They come in all shapes and sizes and many of the best known designers now manufacture and sell their own brand of designer wholesale sunglasses. Athletes from football players to tennis champs can be seen wearing the latest chic brand names and these sunglasses can often cost hundreds of dollars for just one pair.

Sunglasses are much more than just a fashion statement though. With the proper UV coating, sunglasses can protect your eyes against harmful solar radiation. Though most of us have heard the term “UV Rays” and we know that we should protect our eyes and skin when outdoors, you may not be aware of exactly what UV rays are and how they affect us. For those who’ve always wondered exactly what these terms mean and how they affect our health, below is a quick run-down of various terminologies.

  • UVC rays. This type of solar radiation contains the highest energy UV rays, which means they have a greater potential of harming your eyes and skin. The earth’s ozone layer is designed to block virtually all UVC rays. Because of various types of pollution, the ozone layer has broken down and no longer provides adequate protection in many parts of the world. Australia, for instance, has a very high incidence of skin cancer.
  • UVB rays. These rays possess a longer wavelength and lower energy than UVC rays. They are partially filtered by the earth’s ozone layer. In low doses, UVB radiation stimulates the production melanin, which causes skin to darken, creating a suntan.
  • UVA rays. This type of ray is very close to a visible light ray and emits lower energy than both UVB and UVC rays. Though UVA rays are mostly harmless to skin, they can pass through the cornea of your eye and reach the lens and retina causing harm.
  • HEV rays. HEV or High-Energy Visible (AKA Blue Light) radiation may increase your risk of developing macular degeneration. This type of solar radiation is especially harmful for those with low blood plasma levels of antioxidants like vitamin C.

In order to protect your eyes from damaging solar radiation, choose a sunglass that blocks 100 percent of the UV rays. Also, try to find sunglasses that will absorb most HEV rays. If you spend a great deal of time outdoors, then it’s best to wear frames with a close-fitting wraparound style. These provide the best protection because they limit how much light can get to your eyes.
