Children, babies, and those with sensitive skin should always be shielded from long periods of sun exposure. Midday Sun has the strongest UV rays, making it crucial to limit exposure and find shade. 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. Mark this! Snow reflection can nearly double the UV radiation intensity from the Sun.
