What Does Sun Exposure Do to Your Eyes?

Posted on April 9th, 2015

The sun can contribute to several serious eye conditions that may lead to partial vision loss or complete blindness. Optometrists are diagnosing more of these eye care problems as a result of increased sun exposure.


Skin cancer is a well-documented effect of excessive sun exposure. This also applies to the skin around the eyes. Cancerous growths in the eyelids can negatively impact a person’s vision. UV exposure can also lead to cancer of the eye itself, which can result in total vision loss.


Cataracts, or the clouding of the lens of the eye, commonly affect older Canadians. However, optometrists are now treating patients as young as 30 with the same vision problems. Eye care specialists point to UV exposure as the reason behind this increase in cataracts among otherwise young, healthy adults.

Macular Degeneration

UV rays contribute to the deterioration of cells. Because the cornea offers a clear window through which UV rays can enter, the retina can suffer from significant sun damage. When this happens, macular degeneration can occur, resulting in greatly diminished eyesight. To avoid these sun-related eye problems, be sure to wear UV-protected sunglasses and make regular eye exam appointments.
