Anti-fog technology is designed to prevent the formation of fog on surfaces, particularly in environments where temperature changes can cause condensation. This technology is commonly used in products like glasses, goggles, and face shields to enhance visibility and safety. It works by creating a thin, transparent layer that reduces surface tension, allowing moisture to spread evenly instead of forming droplets. There are various methods of applying anti-fog technology, including chemical coatings and special treatments during manufacturing. Some products may also feature hydrophilic materials that attract water, helping to keep surfaces clear. This technology is especially beneficial in activities such as swimming, skiing, and medical procedures.
