Any tips on how to prevent eyeglasses from fogging or developing frost in extremely cold weather.

Richard, anit-fog like CatCrap is only part of the solution. In extreme cold temps a balaclava is necessary, and most will not prevent fogging when wearing glasses unless they have a large downward facing nose shield and mouth breathing holes that allow your warm exhalation to be easily expelled. I have tried many designs over the years...I currently use a Seirus Masque or Ultra Clava, and it worked well at -35F this week with polar bears in the arctic. Slow regulated breathing helps. FYI- ski goggles do not allow your eye to get close enough to the camera viewfinder. 

Best, Chas
