Unlike children, who always need sun protection, most individuals can remain in the sun for up to an hour without getting burnt. The solar radiation is most powerful near the mid-day, so the exposure to the direct Sun should be reduced accordingly. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Mark this! Snow reflection can nearly double the UV radiation intensity from the Sun.
