Protection against the Sun

There are a number of things that we can do to safeguard our health against the effects of increasing UV radiation from the Sun.

Sunglasses that provide 99-100% UV-A and UV-B protection will greatly reduce sunlight exposure that can lead to cataracts and other eye damage. Check the label when buying sunglasses.

A hat with a wide brim offers good sun protection to your eyes, ears, face, and the back of your neck - areas particularly prone to overexposure.

Tightly woven, loose-fitting clothes offer excellent protection against UV radiation. Any clothing is better than none at all.

A sunscreen with protection factor of at least 15 blocks most harmful UV radiation. Apply sunscreen liberally and reapply every 2 hours when working, playing, or exercising outdoors. Even waterproof sunscreen can come off when you dry yourself off with a towel.

The Sun's UV rays are strongest between 10 a.m. and 4 p.m. To the extent you can, limit exposure to the Sun during these hours.

Sunlamps damage the skin and unprotected eyes and are best avoided entirely.
