That visor thing looks pretty cool, but I'm still not sure I trust it not to fog if I've got a balaclava over my nose. Plus, they show someone wearing glasses underneath it, and those glasses are going to fog anyway, probably worse without the wind on them.

I too have almost given up on eye protection. I've tried the dish detergent, but it only does so much. The more you leave on the lenses, the less they fog, but the blurrier things are from the detergent. Wiping the lenses clear, OTOH, seems to remove a lot of the benefit. Also, my wife informs me that the opthomologist told her that dish detergent was bad for them; she didn't remember why. I haven't tried the Cat Crap yet, although I've found that page on the manufacturer's site.

When I'm wearing a balaclava or especially my HeadSock (as I have a lot recently), my eyes don't seem too bad even completely uncovered. Maybe it's the warm air coming up my face from around the nose area. I also wonder if more air comes up over my face rather than down towards my throat because having a full beard blocks it from going down, and that would also explain the lens fogging problem. So anyway, mostly now I just give up and go without eye cover. I generally wear prescription lenses, but my eyesight is not so bad that I can't see to drive (a bike, IMO), and they don't seem too sensitive to the sunlight either, once they are adjusted. Of course, it's easier to do this in clear weather than in snow!
