The Science Behind 3M™ Scotchgard™ Anti-Fog Technology: When microscopic water droplets land on lenses without any type of coating, they bead up and form condensation and fog, obscuring your vision. With 3M™ Scotchgard™ Anti-Fog Technology, the anti-fog coating produces a reduced-contact angle, flattening the water beads into a thin, transparent film of water that allows light to pass through. The 3M™ Scotchgard™ Anti-Fog Coating resists fogging longer than traditional anti-fog coatings, even after washing multiple times. The anti-fogging properties are based on 3M internal testing per EN168 test method when compared to traditional anti-fog coatings.
