Yeah I find it is worse when I wear a mask so I'll have to find one with the nose clip thingy to help a bit, but it still happens without a mask too. I have tried the anti fog spray, I got it from a motorcycle shop and it helps but only a bit.
Ive tried holding the binos as far from my eyes as I can but it only helps for a few more seconds when I do that.
My old man has the exact same problem with his nikons, and we both agree that we can quite literally not glass with out binos for any more then 5 seconds, so its a big issue and i'm surprised to hear that no one else really has this problem.
I reckon they should bring out binos with that rain gaurd covering stuff that bushnell has on its scopes.
This is obviously not a problem right now with the hot weather, but I went for a stroll the other day during the cold snap and it was bout 15 degrees and the binos were useless, so it reminded me to ask you guys.
I'll try the potato juice thing tho cheers.
