Parker’s Perfect anti-fog lens and glass cleaner was designed to keep eyewear and protective eyewear from fogging up in cold or hot, humid conditions. Parker’s anti-fog spray for glasses also contains a cleaner that helps to remove such things as facial oils and sweat.

Parker’s “no fog” lens and glass cleaner also helps keep polycarbonate lenses from scratching on both the inside and outside of the lens. The glasses defogger leaves a protective film that helps to avoid smudges and fingerprints. Its superior anti-static quality also helps to avoid dust and dirt as well as other air born particles from attaching to the surface for easier cleaning. Parker’s anti-fogger has been tested and approved by numerous manufacturers and found to work on most glasses and plastics. This anti-fog spray for glasses is also safe to use on the quality lens coatings of scopes and binoculars. The glasses defogger comes in a 4 oz. spray bottle.
