Ultraviolet light comes from the sun's rays but is invisible to
humans. Two of the three forms of ultraviolet light, UVA and UVB rays, reach
the earth and can damage a person's skin and eyes.
UVA and UVB
rays are reaching the earth at greater intensities because of the thinning of the ozone layer.
A person may look tan soon after being exposed to UVA and
UVB rays. Long-term effects of exposure include premature aging, wrinkling,
skin damage, and sometimes skin cancer.
Tanning booths also use
and transmit ultraviolet light.
