Know the Danger that UV Pose to Your Eyes


Because of campaigns to increase knowledge of the hazards of Ultraviolet (UV) rays to your skin, (which include sunburn and skin cancer), most know about the need for applying sunblock and avoiding direct contact with the sun during outdoor activities. But did you know that UV and other harmful types of radiation from the sun also pose a risk to your eyes?

If you are thinking of leaving the house without sunglasses, reconsider. Extended contact with harmful UV radiation has been seen to be a cause of eye damage.

UV Eye Damage

Exposure to large levels of UV over a short interval is known to result in a ''sunburn of the eye'', leading to pain, blurry vision or even temporary vision loss. Long-term ultraviolet 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 heightened risk of exposure to UV radiation.

UV Eye Protection

For sufficient ultraviolet protection, you should be careful to only purchase sunglasses that keep out 100 percent of UV radiation. Stick with sunglasses that specify they are ''UV 400'', which means 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. Wraparound sunglasses can prevent dangerous UV light from entering from the sides and back of the frame.

You don't have to spend a lot of money on your sunglasses to have proper UV defense, but it's essential to be certain the sunglasses provide complete UV protection. Many less-exclusive brands do offer proper UV coverage. The great news is that as well as defending your eyes from the harmful sunlight, stylish shades are all the rage, so find something you love and have fun in the sun!
