Due to education to increase knowledge of the hazards of Ultraviolet (UV) radiation to your skin, (such as sunburn and skin cancer), most are aware of the importance of using sunblock and avoiding direct contact with the sun 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 threat to your eyes.
If you are considering leaving the house without proper eye protection, think again. Extended contact with the sun's UV rays has been linked to damage to the eye.
UV Eye Damage
Intense UV exposure over a short amount of time can cause a ''sunburn of the eye'', which results in pain, blurry vision or even temporary vision loss. In the long run, UV exposure can result in more threatening eye diseases including cataracts, macular degeneration, and others, which can cause loss of sight. Just like the real thing, tanning beds pose a substantial threat of overexposure to UV.
How to Choose Protective Sunglasses
For effective UV defense, you should be careful to only purchase sunglasses that completely block all UV rays. Stick with sunglasses that specify they are ''UV 400'', which means that they block 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 harmful ultraviolet rays from entering from the sides and back of the frame.
You don't have to pay a lot to have sufficient UV defense, but it's essential to be sure the sunglasses offer full UV protection. Many less expensive brands do offer proper UV coverage. The great news is that as well as defending your eyes from the harmful sunlight, stylish sunglasses are at the height of fashion, so pick up a pair (or two) and let the sun shine down!
