Know the Danger that UV can cause Your Eyes

Most Americans are aware of the dangers of Ultraviolet (UV) rays to your skin, (including sunburn and skin cancer) and the necessity of applying sunscreen and using other protective measures during outdoor activities. But did you know that UV and other radiation from the sun are also a danger to your eyes?

If you are thinking of going outside without proper eye protection, consider this: Continual absorption of the sun's UV rays has been linked to eye damage.

UV Risks to Eyesight

Intense UV exposure over a short amount of time can result in photokeratitis or a ''sunburn on the eye'', leading to pain, blurry vision or even temporary vision loss. Long-term UV exposure can result in more serious eye diseases including cataracts, macular degeneration, and others, all of which can be a threat to vision. Individuals that come into frequent contact with welding machines, tanning beds and lasers are also at increased risk of exposure to UV radiation.

Selecting UV Protective Sunglasses

For effective UV protection, you should select sunglasses that completely block all UV rays. Stick with shades that specify they are ''UV 400'', which indicates that they block all light rays with wavelengths up to 400 nanometers (which includes both UVA and UVB rays, both known to enter the atmosphere).

The size of your sunglasses is also important. Sunglasses with side protection can prevent dangerous ultraviolet rays from coming in through the sides and back of the frame.

Those whose regular activity involves extensive exposure to sunlight are at the most risk for damage to their eyes. UV can be bounced off of bright areas such as snow, water, and white sand and poses the greatest risk from 10 am to 3 pm and during the summer months. Exposure to UV becomes more substantial as you get closer to the equator and at high altitudes. It's recommended that you consult with an eye care professional and to know the hazards of UV exposure. The simple act of putting on your sunglasses can be the key to preserving your precious eyesight.
