Most individuals face no major issues with lengthy exposure to the sun, but children, infants, and individuals with fair skin always require protection. Sun's radiation is most powerful around mid-day, so it's best to limit outdoor activities during this time. 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.
