I have been commuting completely by bike (car-free) for about 5 months and am loving it. The mercury is starting to drop and I plan on continuing my commuting adventure through the cold, snowy mid-western winter.
My winter bike is built up as well as my clothing arsenal. The one thing I can't seem to get right is eye wear. I wear prescription glasses, but they are definitely not enough for fast downhills at 40 degrees or colder. My eyes tear up and it's hard to see. I've considered ski goggles, but they seem like they wouldn't work very well with a bike helmet.
Any suggestions from the world of seasoned winter commuters?
