●Why we need wear the sunglasses to protect ourselves.
Extended exposure to the sun's UV rays has been linked to eye damage, including cataracts, macular degenernation, pingueculae, pterygia and photokeratitis that can cause temporary vision loss.
And new research suggests the sun's may increase your long-term risk of macular degeneration. People with low blood plasma levels of vitamin C and other antioxidants especially appear at risk of retinal damage from HEV radiation.
●Kids Need UV Protection Even More Than Adults
The risk of damage to our eyes and skin from solar UV radiation is cumulative, meaning the danger continues to grow as we spend time in the sun throughout our lifetime.
In fact, some experts say that because children tend to spend significantly more time outdoors than most adults, up to half of a person's lifetime exposure to UV radiation can occur by age 18. (Other research cited by The Skin Cancer Foundation says slightly less than 25 percent of our lifetime exposure to UV radiation is sustained during childhood.)
