Thanks to efforts to increase knowledge of the dangers of Ultraviolet (UV) light to your skin, (including sunburn and skin cancer), most know about the importance of applying UV blocking sunscreen and using other protective measures when spending time in the sun. But how many are aware that ultraviolet rays and other radiation from the sun are also a threat to your eyes?
If you tend to face the sun without proper eye protection, consider this: Prolonged contact with harmful ultraviolet rays has been seen to be a cause of damage to the eye.
UV Eye Damage
Intense UV exposure over a short interval can result in photokeratitis meaning a ''sunburn on the eye'', leading to pain, blurry vision or even temporary vision loss. In the long run, UV exposure can cause more threatening eye diseases such as cataracts, macular degeneration, and others, which can cause vision loss. Individuals that come into frequent contact with welding machines, tanning beds and lasers are also at increased risk of exposure to UV radiation.
How to Choose Protective Sunglasses
To shield your eyes from threatening UV rays, sunglasses should completely block all UV rays. Look for shades that specify they are ''UV 400'', which means that they block both UVA and UVB rays from entering your eyes (400 refers to the wavelength of light in nanometers).
The size of your sunglasses is also important. Sunglasses with side protection can prevent harmful ultraviolet rays from entering from the rear of the sunglasses.
It's not necessary to pay a lot to have sufficient UV coverage, but it's essential to be certain the sunglasses give full UV coverage. More and more manufacturers recognize the importance of offering proper defense from the harmful effects of exposure to sunlight. Further, as well as keeping your eyes safe from the sun's harmful rays, trendy sunglasses are all the rage, so find something you love and have fun in the sun!
