Though the majority can handle prolonged sun exposure, it is crucial to always shield babies, children, and those with fair skin. The Sun is most powerful around mid-day, so it's a good practice to reduce direct exposure. 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. Caution! The reflection of snow can nearly double the intensity of the Sun's UV radiation.
