Anyone had any issues with the Meopta binocular fogging up on the lense closest to your eye?  It quickly disipates, but is rather annoying.  I didn't even think the weather was too humid to be fogging up this easy.

Are you referring to exterior fogging?

All glass has some external fogging.  If you clean them with some anti-fogging stuff it helps.

 It's probably the moisture from your breath condensing on the colder lens surface.
 It will occur in cool weather.

It can also come from the heat coming from your face (without coming close to breathing on the lens) if it is wet and cool enough, or from the heat from expelled breaths rising past the ocular, even if you don't breathe on the lens.  I tend to be a bit of a hothead in this regard and sometime have this happen with me.  One thing that will help is (especially if you are perpetually plagued with this problem) is to choose 6-7x binocular with lots of eye relief, so when the eye cup is extended it keeps your face a bit further from the ocular lens.  Doesn't help much I suppose if you have to wear glasses, which I don't.
 
We loose a lot of body heat through our heads, so sometimes when it is cold, we can tend to trap heat around the face by bundling up against the chill.  The trick is to find a balance so you can keep warm enough but not collect too much heat around your head.
 
I would not suspect a Meopta to be either more or less susceptible to this than another binocular.

 Very well-explained.
 If you can do so, keeping the ocular lenses very warm just prior to using them should also help, as it would not condense the vapor until the lenses cooled down enough.

Thanks for the replies.  I guess it would have to be from the heat from my head.  This morning I was using them and it was probably 50 degrees with some humidity in the air and they were fogging at first.  Probably they were at first is because I was warmer at first and finally cooled down.  Good explanations though.
 
What would you recommend I put on the lense to help some of the fog?

There are two different products designed for that I know of, one is Parker's Perfect and the other is called No-Fog.
