The sun's primary danger to us comes in the form of UV light or radiation. UV radiation is a component of solar radiation. Artificial sources like welding machines, tanning beds, and lasers can also give off UV radiation.

There are three types of UV radiation. UV-C is absorbed by the ozone layer and does not present any threat. UV-A and UV-B radiation can have adverse long- and short-term effects on the eyes and vision.

Both long- and short-term exposure to UV radiation can harm the eyes, affect vision, and compromise overall eye health.

There are several eye diseases and conditions caused or aggravated by exposure to UV radiation:

Macular Degeneration.

Cataracts..

Pterygium. Often called "surfer's eye."

skin cancer. Skin cancer in and around the eyelids is also linked to prolonged UV exposure.

Photokeratitis. Also known as corneal sunburn or "snow blindness."
