How to taking a few simple, correct precautions can help reduce your risk of exposure to ultraviolet rays:
Avoid going out in the sun between 9:00 a.m. and 2:00 p.m.

Sunglasses with large lenses that block 99-100 percent of UVA and UVB rays, often labeled “UV Absorption up to 400 nm” or “Meets ANSI UV Requirements.” If sunglasses are only able to block 70 percent of UV rays, they will be labeled as cosmetics. Sunglasses that do not block UV rays will be labeled as cosmetics. They may not be labeled. However, the intensity of the lens tint does not indicate any UV protection properties.
do not protect against UV rays 100 percent, but research has shown that using a parasol along with sunscreen protects the body from UV rays more effectively than using an umbrella alone.
