Ultraviolet (UV) rays are invisible rays that are part of the energy that comes from the sun. UV rays can burn the eyes, hair, and skin if these parts of the body are not properly protected, or if they undergo too much exposure to the sun. Nevertheless, they are very useful in our ecosystem.
Anyone who spends time in the sun, even for short periods of time, stands to benefit from some type of UV protection. UV protection includes chemical formulas, apparel, and glasses designed to protect the skin and eyes from harmful UV rays. The first step in selecting the right kind of UV protection starts with understanding UV rays.
It is widely known that excessive UV-A and UV-B rays cause sunburn and skin cancer, but fewer people realize they also cause sunburned eyes.
