Know the dangers. UV rays can come from many directions. They radiate directly from the sun, but they are also reflected from the ground, from water, snow, sand and other bright surfaces. 

Wear proper eye protection and hats to block the UV rays. To provide adequate protection for your eyes, sunglasses should:

• Block out 99 to 100 percent of both UV-A and UV-B radiationScreen out 75 to 90 percent of visible light
• Be perfectly matched in color and free of distortion and imperfection
• Have lenses that are gray for proper color recognition

If you spend a lot of time outdoors in bright sunlight, wrap around frames can provide additional protection from the harmful solar radiation. Lastly, don’t forget about protection for your children and teenagers, as they typically spend more time in the sun than adults.
