binoc fog problems

[jc502]

What do you do to keep your binoculors from fogging on the outside in cold weather? I have tried everything, including scuba divers anti-fog, 3 or 4 lense anti-fog brands, and nothing works real well. Some work better than others, but all eventually fail. What happens is my binocs get cold and when I bring them to my face they steam up. I really don't like sticking them in my jacket. They have o-rings and nitrogen filled, and I am certain it is on the outside. The best I have used is called "Parker's Perfect". It gives me the most use , but still fogs up after 10 seconds and then you have to put them down for a minute or two.

Have you tried the Zeiss anti- fogging spray? It seems to work pretty good but I haven't tried any others so I have nothing to compare it to.

If you are wearing a face mask, try pulling your face mask down before you bring the binos to your face. That way your breath isn't directed right into you eye cups... That was my problem, pulling the mask down fixed it...
