Given the potency of the midday Sun's UV radiation, one should avoid prolonged exposure. 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. Bear in mind! The Sun's UV radiation can nearly double in intensity due to the reflective quality of snow.
