HOW UV IMPACTS YOUR EYESDid you know that one in three American adults experience symptoms of UV exposure*?
But how do you know if your eyes are feeling the effects of the sun? Here’s a look at some common effects of UV exposure on your eyes.

THE ABC'S OF UVThe sun emits three types of ultraviolet radiation. Here’s what you need to know about each.
UVA Less harmful than UVB or UVC but the most common type you come into contact with. UVA penetrates the atmosphere completely. UVB Very harmful with continued exposure. Some UVB rays are absorbed by the atmosphere. UVC The most harmful of the three. Fortunately, the atmosphere completely filters out UVC radiation. |
8 FACTORS THAT INCREASE YOUR
EXPOSURE TO ULTRAVIOLET RADIATION
EYE COLOR
Blue eyes contain less of the protective pigment melanin than brown eyes, which could be a cause for increased vulnerability to UV. 
TIME OF YEAR
Unsurprisingly, UV levels are highest during the summer months in the U.S. |
AGE
Children generally receive 3x the annual UV exposure of adults, and their developing eyes are especially vulnerable to UV-related damage. 
OCCUPATION
From construction workers to crossing guards, if you work outdoors, you should be protecting your eyes. |
GEOGRAPHY
States in the southern half of the U.S. receive more intense UV rays than those in the north, due their proximity to the equator – and therefore the sun. 
TIME OF DAY
UV levels are highest in the U.S. from 8 a.m. – 10 a.m. and 2 p.m. - 4 p.m. |
ALTITUDE
Those majestic peaks may make for amazing views, but they also up the UV intensity because the thinner atmosphere filters less of the sun’s radiation. 
ENVIRONMENT
Reflected UV from water, snow, ice, and even concrete is also damaging to your eyes. |
