When the Sun's UV radiation is most intense during midday, it's best to find shade and limit 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. Heed this! Snow reflection can almost augment the UV radiation of the sun by double.
