1, Use Sunglasses

Ultraviolet-absorbing eyewear provides the greatest measure of UV protection. Examine labels carefully to ensure that the lenses absorb at least 99 to 100 percent of both UV-A and UV-B. Be wary of labels that claim "Provides UV Protection" without specifying exactly what percentage of UV rays the product blocks.

2, Use hats or caps

What you may not realize is, a pair of sunglasses is not the only thing to protect your eyes. Either a hat or a cap will signicantly reduce the sun rays too. Using both a brimmed hat or cap and UV-absorbing eyewear can provide protection from sunlight. A wide-brimmed hat or cap will block roughly 50 percent of the UV radiation and reduce the UV radiation that may enter the eyes from above or around glasses.
