Anti-fogging coatings are special treatments applied to surfaces, such as glasses or goggles, to prevent fogging. These coatings work by reducing surface tension, allowing moisture to spread evenly across the surface instead of forming droplets. This helps maintain clear visibility in various conditions, such as when transitioning from cold to warm environments. These coatings are commonly used in sports eyewear, safety goggles, and diving masks. They can be either permanent or temporary, with some requiring reapplication after a certain period. Anti-fogging technology is essential for enhancing safety and performance in activities like swimming and skiing.
