Be constantly cautious; skin and eyes can be quickly affected if left unprotected. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. A sunscreen boasting a minimum SPF of 30 should be generously applied and reapplied even on cloudy days, post swim or outdoor exercise. Watch out! Sand and water enhance the UV exposure you receive.
