When engaging in indoor or outdoor activities, clear vision is vital. GEAR AID Anti-Fog Spray ensures your eyewear and protective lenses stay clean and fog-free. Its alcohol-free formula prevents fogging on dry lenses, including non-AR eyeglasses, sunglasses, swim goggles, and face shields. With its concentrated formula, one 0.5 fl oz bottle can treat multiple lenses. Just a quick spray, followed by buffing or rinsing, is all it takes.
