Aug. 24, 2009— -- Question: How do sunlight and radiation affect my risk of developing an eye problem?

Answer: Sunlight and other forms of radiation may have a negative impact on various structures of the eye. Ultraviolet radiation can particularly affect the lens of the eye and the cornea. Exposure to ultraviolet radiation from a welding torch can cause a burn to the front of the eye. Excessive ultraviolet radiation may promote cataract development.

Usually, ultraviolet radiation does not penetrate to the back of the eye, but blue light, which is a component of white light especially in sunlight, has the ability to cause damage in excessive amounts. For that reason, it's important to wear adequate sun protection.
