The ZEISS Fog Defender System is a two part anti-fog kit containing a 0.5 fl oz spray bottle and a 5 inch by 5 inch microfiber cloth. The spray leaves a thin hydrophilic film on the lens that keeps it fog free for up to 72 hours. The cloth supplied in the kit is the one used to work the formula across the lens and is needed for the intended result.
An anti-fog spray is the format chosen by people who want a longer interval between applications than a single use wipe gives, and this kit is compact enough to store in almost any bag. Both sides of the lens are sprayed and then wiped until dry, which under normal use means one application every three days or so. It suits glasses, sunglasses, binoculars, camera lenses, swim goggles, ski goggles and face shields, and it can be used while wearing a face mask.
