Review on Premium Anti Fog Paste for Eye & Sunglasses - Fog-Free Lens Cleaning Solution for Clear Vision and Maximum Protection by Jessica Morris

Basically to reduce fogging on my lenses when wearing face masks. The trick is rubbing your finger over it, letting the film dry and then wiping it down with the cloth that comes with it, and that's the really tricky part. Swipe too much and it won't work, don't wipe enough and everything will be blurry. The problem is that even if everything is perfect I have a few hours before my glasses fog up again. I am comparing this to the Cat product which seems to have the best formulation lasting 2-3 days but I am definitely using that stuff with this one. Save this for ski season see if it holds up when I wear goggles over goggles but not good enough for Covid face masks.
