Sun exposure does not present considerable issues for many, yet infants, fair-skinned people, and children necessitate constant protection. The solar radiation is most powerful near the mid-day, so the exposure to the direct Sun should be reduced accordingly. 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. Remember to consider! The UV radiation from the Sun can be intensified nearly twice by the reflection of snow.
