Health Canada's role is to help Canadians maintain and improve their heath. As part of this work, Health Canada promotes public awareness about sun safety and the harmful effects of UV radiation.

Most of the damage caused to eyes by UVB and UVA rays happens over a long period of time and cannot be reversed. Sensitivity to UV rays varies from one person to the next.

Blue light is visible light in the blue portion of the colour spectrum. The intense glare of light reflecting off snow or water contains blue light. Your eyes cannot focus clearly in blue light. Some scientists believe that routine exposure to blue light over many years may age the retina and increase the risk of blindness in some people over the age of sixty.

UV rays carry more energy than visible light rays, so the eye is at greater risk of damage from absorbing UV rays than from absorbing other kinds of light. There are two types of UV rays that reach the Earth's surface: UVA and UVB. These rays can cause, or speed up the progress of, several diseases that affect the eye or its supporting structures. UVB rays have also been linked to skin cancer.

If eyes are overexposed to UV radiation, the front portion of the eyes can be damaged. If visible light is too bright or intense, or if you stare directly at the sun, even briefly, the retina can be damaged, causing permanent loss of vision. UV radiation, along with wind and drying of the eye, may cause snow blindness, an uncomfortable but temporary condition.

When your eyes absorb ultraviolet radiation and visible light from the sun, heat or chemicals react in eye tissue. These reactions can cause permanent damage if the eye's natural ability to heal itself is overwhelmed.

There is some evidence that daily exposure to UV radiation in very bright sunlight over many years may increase the risk of developing cataracts. Cataracts cause a gradual clouding of the natural lens of the eye.
