Sunburn most commonly happens between 10 am and 3 pm, when ultraviolet (UV) rays are at their strongest. Wear sunscreen with a sun protection factor (SPF) of 15 or greater, when you expect to be out in the sun for more than 15 minutes (a little sun is good for you, see Tip 45). Ladies will also benefit by wearing facial makeup containing SPF. Sunlight can damage the sensitive cells of the macula (the central part of the eye that is responsible for most of our vision), so, be sure to wear sunglasses (pick shades that block 99% of UV-A and UV-B rays), and wear a wide-brim hat.
