The majority are not significantly affected by prolonged sun exposure. Infants, children, and those with fair skin must always have protection. The best time to avoid the Sun's harmful UV radiation is during midday when it's most potent. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Beware! The strength of the UV rays is increased nearly double-fold by the reflection of the snow.
