Without any glasses, double-pane goggles work great if you have good ones. I have some simple Scott goggles that I wear with a balaclava and have no fogging issues whatsoever, but I don't have glasses. Today's ride was my coldest so far this winter at 3 F and we did just fine. The foam "surround" on the goggles keeps the exhaled air from getting into the goggle area.
It was pretty cool to get back and look in the mirror to see all the frost around the edges of the balaclava where the exhaled air was moist and froze.
I use safety glasses for reasons I described above, and also the rigid eyepieces allow me to wear my favorite eyeglass-mounted mirror.
I too checked myself in the mirror after a coworker commented on my appearance after yesterday's commute. In another winter thread I wrote:
