Protect your eyes from UV raditation
How Does UV Light Affect Eyesight?
Both long- and short-term exposure to UV radiation can harm the eyes, affect vision, and compromise overall eye health. There are several eye diseases and conditions caused or aggravated by exposure to UV radiation, such as:
- Macular Degeneration. Macular Degeneration (AMD) is caused by damage to the retina over time and is the leading cause of age-related blindness. Extended exposure to UV light increases your risk of developing macular degeneration.
- Cataracts. A cataract is a clouding of the eye’s natural lens — the part of the eye that focuses the light we see. UV light, especially UV-B rays, increases your risk for certain types of cataracts. It is estimated that 10% of all cataract cases are directly attributable to UV exposure.
- Pterygium. Often called “surfer’s eye,” pterygium is a pink, non-cancerous growth that forms on the layer of conjunctiva over the white of your eye. UV light from the sun is believed to be a factor in the development of these growths.
- Skin Cancer. Skin cancer in and around the eyelids is also linked to prolonged UV exposure.
- Photokeratitis. Also known as corneal sunburn or “snow blindness,” photokeratitis is the result of high short-term exposure to UV-B rays. Long hours at the beach or skiing without proper eye protection can cause this problem. It can be very painful and may cause temporary vision loss.
How Can You Protect Your Eyes from UV Light?
Know the dangers. UV rays can come from many directions. They radiate directly from the sun, but they are also reflected from the ground, from water, snow, sand and other bright surfaces.
Wear proper eye protection and hats to block the UV rays. To provide adequate protection for your eyes, sunglasses should:
- Block out 99 to 100 percent of both UV-A and UV-B radiation
- Screen out 75 to 90 percent of visible light
- Be perfectly matched in color and free of distortion and imperfection
- Have lenses that are gray for proper color recognition
Sunglasses protect your eyes from UV rays and reduce the risk of cataracts. They also protect the tender skin around your eyes from sun exposure. Sunglasses that block both UVA and UVB rays offer the best protection.
If you spend a lot of time outdoors in bright sunlight, wrap around frames can provide additional protection from the harmful solar radiation. Lastly, don’t forget about protection for your children and teenagers, as they typically spend more time in the sun than adults.
Be sure to see us at least every two years for a comprehensive eye examination. It is a good way to monitor your eye health, maintain good vision and keep track of your solar radiation protection needs as well as new advances in eye protection.
