Unlike children, who always need sun protection, most individuals can remain in the sun for up to an hour without getting burnt. Direct Sun exposure should be minimized especially during midday when radiation is most intense. 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. Mind you! Snow reflection can increase the intensity of the Sun's UV radiation nearly twofold.
