Zeiss AntiFOG spray is a cost-effective solution to keep your spectacle lenses from fogging up for up to 72 hours. The spray is easy to use and leaves behind a thin film on the lenses, ensuring that fine, condensed water droplets cannot adhere to the lens surface. This product can be used with coated snow goggles, sunglasses, helmet visors, ski, swimming and diving goggles as well.
