The sun emits radiation in the form of ultraviolet (UV) radiation. UV radiation is at its highest when and where the sun's rays are the strongest. This means that UV levels will be highest around noon on a clear sunny day, as well as during the summer months. UV levels will also be highest near surfaces that reflect sunlight, such as water, snow and sand. Exposure to UV can cause sunburn, skin aging, skin cancer and eye damage. While skin cancer is largely preventable, it is the most common form of cancer in the United States - over 3.5 million new cases of skin cancer are diagnosed each year.
