Sunlight and Your Eyes
The primary source of UV related injury to the eye, is sunlight. Dozens of studies suggest that spending long hours in the sun without eye protection increases the chances of developing eye diseases, including cataracts. Even low amounts of sunlight can increase the risk of developing eye disorders, as was found in the 1998 Journal of the American Medical Association. The American Academy of Ophthalmology has cautioned that excess exposure to UV radiation may increase the incidence of cataracts. Cataracts are a form of eye damage that causes the loss of transparency in the lens, clouding vision. Every person is susceptible to cataracts. "Snow Blindness", or a burning of the eye surface is another potential effect of UV radiation. The effects usually disappear within a couple of days, but may lead to further complications later in life. UVB damage to the eyes is also cumulative, so it is never too late for people to start protecting their eyes.
Sunglasses help you in two very important ways. First, they filter light and second, they protect your eyes from damaging ultraviolet (UV) rays. Mounting evidence shows that exposure to UV rays can damage your eyes. Long-term exposure to UV rays can lead to cataracts, macular degeneration, or skin cancer around the eyelids. Sunglasses should be worn when you are outdoors so you can protect your eyes. The rule of thumb is, the more expensive and the more known the manufacturer of the sunglasses the more protection. Cheaper sunglasses look good but maximum protection is not guaranteed.
Sunglasses Protection
Impact Protection
Some sunglasses also pass ANSI Z87.1 requirements for basic impact and high impact protection. These are voluntary standards, so not all sunglasses comply. In the basic impact test, a 1" (2.54 cm) steel ball is dropped on the lens from 50" (127 cm). In the high velocity test, a 1/4" (6.35mm) steel ball is shot at the lens at 150 ft/s (45.72 m/s or 165 km/h). In both tests, no part of the lens can touch the eye for the glasses to pass the test..

Proper selection of sunglasses should be ensures as it is the matter of your eyes. Nowadays sunglasses of many companies are available in the market like the famous Oakley sunglasses.
