How to stop your diving mask or goggles from fogging up

I hate to be this guy but....Your mask fogs because, during the manufacturing process, the lenses get coated with a thin layer of silicone. The anti-fog isn't working because it binds to the silicone layer, not the glass. Rubbing your finger on the glass with force removes the silicone layer. Some people burn it off (not recommended on modern silicone masks), some use commercial lens scrubs, and some use toothpaste. It's all doing the same thing, removing the silicone layer. There are many videos available about this. It has nothing to do with the "micro fissures of the glass."

Amazing! This works

Thank you I'm gonna try this out.
