Darn glasses keep fogging up-advice please!

Dear Blind Canadian,

Lasic surgery.

Or wait it out.  With global warming Manitoba will be the next Arizona in a few years.

Very similar situation as you, and I'm 6' 2-1/2".  I fanagle the best I can with trying to breathe more downwards to avoid my breathe rising and fogging up my glasses.  It takes some getting used to.

This might seem odd, but I had a similar problem with my Oakley running glasses.  I found that if I kept my eyebrows trimmed very short, and I wore them an inch or so extended from my face, my glasses didn't fog up. 

Turns out, when I wasn't trapping the hot air between my glasses and my eye sockets, they didn't fog up.

Not sure if this will work for you - but something to consider b/c they are fogging up b/c you are trapping heat inside the lenses.

My glasses fog up when I have my mouth & nose covered.  The neck-gaiter I wear funnels the warm air up and it gets into my glasses.  I haven’t really found a way to prevent it other than pulling the gaiter down periodically to let the glasses clear or just trying to go without it for as long as I can. 

I’ve seen those neoprene that some skiers/snowboarders wear over their nose/mouth that have the little vent-holes over the mouth. Maybe they would work? 

There are more sophisticated face masks, like mentioned above.

I have also had success with the eyebrow/leaving space trick.  If you leave a little bit of room, you should be good.  Close enough that the glasses stay warm, but far enough for good airflow.  Resist the urge to push them up your nose. I wear glasses and I know it's hard not to do that.

I ran at 4F last week and didn't need to keep my nose covered after a quick warmup, but the breath deflecting from my balaclava was sending up moisture.  I made the mistake of taking my (sun)glasses off and then they promptly froze.  Oops!  After a quick wipe and repositioning it was fine the rest of the run.
