Doctor Klaus Antifog Spray minimizes condensation and speeds up the defogging process on all types of lenses. Effectively prevents fogging on eyeglasses, sports glasses, swimming goggles (in pools or open water), ski masks, helmet visors, and personal protective equipment. Benefits include superior anti-fog protection, gentle cleaning, and a renewed clarity for your lenses. Simply spray on both sides of the lenses, wait 20 seconds, then wipe with a microfiber cloth using smooth, vertical strokes (avoid circular motions). Apply just before temperature changes (warm to cold air) for optimal results. Reapply after each temperature change to maintain anti-fog performance.
