The ABC's of UV

The sun emits three types of ultraviolet radiation. Here’s what you need to know about each.

Less harmful than UVB or UVC but the most common type you come into contact with. UVA penetrates the atmosphere completely.

​Very harmful with continued exposure. Some UVB rays are absorbed by the atmosphere.

​​The most harmful of the three. Fortunately, the atmosphere completely filters out UVC radiation.

8 Factors That Increase ​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.

Age icon


Children generally receive 3x the annual UV exposure of adults, and their developing eyes are especially vulnerable to UV-related damage.

Geography icon


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.

Altitude icon


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.

Time of Year

Unsurprisingly, UV levels are highest during the summer months in the U.S.
