Extended exposure to the sun's UV rays has been linked to eye damage, including cataracts, macular degeneration, pingueculae and pterygia and photokeratitis that can cause temporary vision loss.
To protect your eyes from harmful solar radiation, sunglasses should block 100 percent of UV rays and also absorb most HEV rays. Frames with a close-fitting wraparound style provide the best protection because they limit how much stray sunlight reaches your eyes from above and beyond the periphery of your sunglass lenses.
The ultraviolet radiation element in sunlight is divided in two basic areas - UVA and UVB. Sunglasses block both of these types of rays. What exactly is UVA and UVB you ask? Well, UVA represents the ultraviolet radiation that passes through the Earth's ozone layer, reaches our skin and can lead to premature aging. UVB are also ultraviolet rays, but are absorbed, in great amount, by the ozone layer. Still, they are very harmful and can contribute to the cause of skin cancer and cataracts.
The benefit of super light polarized sunglasses is great as applied to golfing and fishing and other sports. Super light polarized sunglasses allow clarity and comfort during outside activities. This combined with UV protection can be a preventative measure for eye disease. They can also be very stylish and with a lighter frame you can be comfortable wearing your super light polarized sunglasses.
As the damage of ultra violet radiation to eyes is irreversible, it is so important for us to protect our eyes from the inevitable damage as early as possible.
