Children must always have sun protection, unlike most people, who can tolerate up to an hour in the sun without any burns. Sun's radiation is most powerful around mid-day, so it's best to limit outdoor activities during this time. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage. Caution! The reflection of snow can nearly double the intensity of the Sun's UV radiation.
