Early Winters catalogs sell an anti-fogging stuff that works quite well.
I've used it mainly on the visor of my motorcycle helmet in cold 
weather.  It dries clear (unlike the other suggestion, above) and a small
bottle lasts a long time.  Early Winters claims it the same stuff NASA
uses on space-suit helmet visors.

Actually, I think they just have a couple guys in a back room spitting
in little bottles and mailing them off to customers :-).
