Children necessitate constant protection from sunlight, unlike the majority, who can remain under the sun for about an hour without burning. The Sun is most powerful around mid-day, so it's a good practice to reduce direct 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.
