By now, most Americans are familiar with the threats of Ultraviolet (UV) light to your skin, (including sunburn and skin cancer) and the need for using sunscreen and using other forms of sun protection particularly during the blazing summer months. What is less known is that ultraviolet rays and other harmful types of radiation from the sun are also a risk to your eyes.
If you often leave the house without proper eye protection, think about this: Frequent contact with the sun’s ultraviolet radiation has been shown to cause damage to the eye.
UV Eye Damage
Intense UV exposure over a short amount of time is known to result in a ”sunburn of the eye”, leading to pain, blurred vision or even temporary blindness. Long-term UV exposure can lead to more serious eye diseases including cataracts, macular degeneration, and others, all of which can cause loss of sight. Just like the real thing, tanning beds pose a serious risk of overexposure to UV.
UV Eye Protection
To guard your eyes from threatening UV rays, you should select sunglasses that keep out 100 percent of UV radiation. Stick with shades 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 block dangerous ultraviolet light from entering from the sides and back of the frame.
You don’t have to empty your pockets to have sufficient UV defense, but it’s essential to be sure the sunglasses provide complete UV coverage. More and more manufacturers recognize the importance of offering proper defense against the threatening effects of exposure to UV light. The great news is that as well as keeping your eyes protected from the harmful sunlight, trendy sunglasses are all the rage, so find something you love and have fun in the sun!
