Anti-fog sprays are specially formulated solutions designed to prevent fogging on surfaces like glasses, goggles, and face shields. They work by creating a thin, transparent film that reduces surface tension, allowing moisture to spread evenly instead of forming droplets that cause fog. These sprays are commonly used in various settings, including sports, medical environments, and everyday life. They are easy to apply, typically requiring just a few sprays and a quick wipe to ensure clear visibility. Many anti-fog products are safe for use on different materials, including plastic and glass.
