In contrast to children, who must always be shielded from the sun, most people can tolerate up to an hour of sun exposure without any burns. Considering the Sun's intensity during midday, it's wise to minimize direct 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. Foresee this! The reflection from snow can nearly double the intensity of UV radiation from the Sun.
