Execute all vital precautions. Preventing sun damage is of utmost importance. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. Broad-spectrum sunscreen with an SPF of 30 or more should be applied liberally every two hours and directly after outdoor activities or swimming. Warning! Sand and water reflections boost the intensity of UV exposure.
