I was just thinking,what about the stuff scuba divers put on there mask to keep them from fogging up?
Eye doc here...
Generally saliva was used by most divers when I dove... I heard peanut butter works, but found it just made a mess.
They to make coatings for lenses that help in fogging, but you need to apply an activator. There are supposedly sprays that are supposed to help with fogging, and I tried some on my diving mask when I dove, but saliva worked better (of course that was some years ago and there have supposedly been some improvements).
A good anti-glare coating will help reduce fogging... A cheap coating will increase it.
