Anti-fog cloths are specially designed fabrics that help prevent fogging on surfaces like glasses, goggles, and screens. They are often treated with a solution that reduces surface tension, allowing moisture to spread evenly and evaporate quickly, which keeps the surface clear. These cloths are commonly used by people who wear eyeglasses, safety goggles, or swimming goggles. They are also popular among photographers and sports enthusiasts who need to maintain visibility in various conditions. Anti-fog cloths are reusable and can be an effective solution for improving visibility in humid or temperature-changing environments.
