ZEISS Fog Defender System anti-fog spray is an easy-to-use solution to prevent optical lenses from fogging up. Simply spray the formula onto the lens surface and wipe until dry with the included cloth, providing up-to 72 hours of fog prevention.
The special anti-fog solution leaves behind a thin hydrophilic film on the lenses. This ensures that fine, condensed water droplets do not adhere to the lens surface, preventing lenses from fogging.
ZEISS Fog Defender System can be used on eyeglasses, face shields, snow goggles, visors and many other optical surfaces.
