Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. A sunscreen with at least SPF 30 should be used liberally and reapplied frequently on cloudy days, especially after swimming or an outdoor workout. Alert! UV radiation becomes sharper due to reflections from sand and water.
