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. Protect yourself by liberally applying a sunscreen of at least 30 SPF. Sunscreen prevents sunburn and decreases the damaging effects of Sun's radiation on the immune system.
