Light protection refers to methods and materials used to shield individuals or objects from harmful effects of light, particularly ultraviolet (UV) radiation. This is important in various settings, such as in homes, workplaces, and outdoor environments, to prevent skin damage, fading of materials, and other adverse effects caused by excessive exposure to sunlight. Common forms of light protection include the use of sunscreen to block UV rays on the skin, UV-filtering window films for buildings, and protective clothing designed to cover the skin. Additionally, sunglasses with UV protection help safeguard the eyes from harmful light exposure while outdoors.
