The sun releases energy, called radiation, in various forms: in the sunlight you see, the heat you feel and the invisible ultraviolet (UV) rays that cause you to get sunburned. UV rays from the sun can also damage your eyes and hurt your vision.
Proper Eye Protection
Adequately protecting your eyes from the sun, and other elements like wind or water, is crucial to main-taining your vision and eye health.
Use everyday eyewear that absorbs UV rays:
All types of eyewear, including prescription and nonpre-scription glasses, contact lenses and lens implants, should absorb UVA and UVB rays. For UV pro- tection in everyday
eyewear, there are several options like UVblocking lens materials, coatings and photochromic lenses.
Select the right sun-glasses:
Sunglasses help in two important ways:
they filter light, and they protect the eyes from damaging UV rays. Look for labels that state they block 99-100% of UVA and UVB rays. They should also reduce glare, protect your entire eye area, be comfortable to wear and don’t distort color.
Wear a brimmed hat or cap:
A wide-brimmed hat or cap will block about half of UV rays, and also limit UV rays that hit the eyes from above or around glasses.
