Anti-fog swimming goggles are designed to provide clear vision by preventing the lenses from fogging up during use. This is achieved through special coatings and treatments applied to the lenses, which reduce condensation and maintain visibility.
Anti-fog coatings typically consist of hydrophilic (water-attracting) materials that spread moisture evenly across the lens surface, preventing the formation of fog. Some advanced coatings are embedded into the lens material during manufacturing, offering longer-lasting protection compared to surface-applied coatings.
