The ZEISS AntiFOG Kit twin-pack provides safe and effective fog-free vision. It creates a thin film, comparable to an additional coating, to protect lenses from fogging up. This makes it great for use with face masks, when drinking hot drinks, and in all weather conditions. The anti-mist spray provides effective fog-free vision for up to 3 days for all eyewear. It is quick, gentle, and easy to use, leaving lenses clear and streak-free. The formula is safe for all lenses, including optical lenses. It is ideal for spectacles, reading glasses, sports visors, fashion eyewear, cycling shades, safety helmets, sunglasses, ski goggles, camera lenses, and more. This convenient and portable set is for use at home or on-the-go. It contains 15ml anti-fog spray and a large treated polishing cloth.
