PROTECT YOUR EYES FROM HARMFUL UV RAYS & CUT YOUR RISK OF CATARACT AND CANCER

Long-term exposure to UV rays has been linked to skin cancer around the eyelids. Sunscreen is essential to protecting your skin, but a good pair of sunglasses will help protect your eyes, now and as you age, said Daniel D. Garrett, Prevent Blindness America spokesperson.

One of the risk factors for developing cataracts is long time exposure to UV rays. Cataract is the most prevalent age-related eye disease in the world, and according to the World Health Organization, the leading cause of blindness. There are nearly 20.5 million Americans age 40 and older with cataract. Cataract affects more than half of all Americans by the age of 80, so anything you can do to cut your risk is advised, added Garrett.

UV radiation in sunlight, including both UV-A and UV-B, has been shown to be harmful to the eye. Constant exposure to bright sunlight can damage the cornea (the clear outer part of the eye that allows lights through to the retina), the lens (the part of the eye responsible for focusing), and the retina (the innermost layer of the eye that sends an image to the brain). The risk is greatest at midday, from 10 a.m. to 3 p.m. and during summer months. Anyone who spends long hours on the beach or ski slopes without proper eye protection is at risk of developing photokeratistis - sunburn on the cornea. While it is not permanent, corneal sunburn can be extremely painful and result in temporary loss of vision.

Pterygium is another UV-related risk. Pterygium is benign tissue growth that starts in the white of the eye, but may extend to the cornea. Eventually, the growth blocks vision and surgery is necessary to remove it. Athletes and people who work outdoors in the sun and wind are at greatest risk of developing this condition.

While some professions and climates put people at greater risk, the best defense for everyone is to wear sunglasses that screen 99 to 100 percent of UV rays and brimmed hats said Garrett. It is also very important to protect children's sight from the damaging effects of the sun - choosing unbreakable, well-fitted sunglasses and a hat that shades the face is the best way. PBA offers several free fact sheets to help you protect your sight: UV Awareness Quiz, Sunglasses, and Selecting Sunglasses for Children.
