Know the Dangers of Ultraviolet Rays for Your Eyes


Due to efforts to create awareness of the threats 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 how many are aware that ultraviolet rays and other radiation from the sun are also a threat to your eyes?

If you are considering leaving the house without sunglasses, think about this: Continual contact with harmful ultraviolet rays has been seen to be a cause of damage to the eye.

UV Risks to Vision

Excessive short term exposure to UV is known to cause a ''sunburn on the eye'', leading to pain, blurred vision or even temporary blindness. In the long run, UV exposure can result in more threatening eye diseases such as cataracts, macular degeneration, and others, all of which can cause loss of sight. 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 sufficient ultraviolet defense, you should be careful to 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 block harmful UV rays from entering from the rear of the sunglasses.

You don't have to spend a lot of money on your sunglasses to have proper UV defense, but it's essential to be sure the sunglasses give full UV defense. Many less-exclusive brands do offer proper UV coverage. The great news is that as well as keeping your eyes safe from the hazards of UV exposure, trendy sunglasses are at the height of fashion, so find something you love and have fun in the sun!
