Thanks to campaigns to inform the public of the dangers of Ultraviolet (UV) radiation to your skin, (including sunburn and skin cancer), most know about the importance of using sunscreen and using other protective measures when spending time in the sun. But did you know that UV and other harmful types of radiation from the sun are also a threat to your eyes?
If you tend to leave the house without sunglasses, think about this: Continual absorption of the sun's UV radiation has been seen to be a cause of damage to the eye.
Risks of UV Eye Exposure
Exposure to excessive levels of ultraviolet radiation over a short amount of time is known to lead to photokeratitis which means a ''sunburn on the eye'', leading to pain, blurry vision or even temporary vision loss. In the long run, UV exposure can cause more serious eye diseases such as cataracts, macular degeneration, and others, which can cause vision loss. Just like the real sun, tanning beds pose a substantial risk of overexposure to UV.
UV Eye Protection
To shield your eyes from harmful UV rays, sunglasses should completely block all UV rays. Look for sunglasses that specify they are ''UV 400'', which means that they prevent all UV light from entering your eyes (400 refers to the wavelength of light in nanometers).
You also want to choose sunglasses with full eye coverage. Wraparound sunglasses can prevent dangerous UV light from entering from the sides and back of the frame.
It's not necessary to spend a lot of money on your sunglasses to have proper UV protection, but it's essential to be certain the sunglasses offer complete UV coverage. More and more manufacturers recognize the importance of offering proper defense against the threatening effects of exposure to sunlight. Further, in addition to keeping your eyes safe from the sun's harmful rays, stylish shades are in style, so find something you love and have fun in the sun!
