Wipers please!

I need windscreen wipers. For my glasses, that is. This morning was the second foggy morning for the winter (Monday was the first)... and my glasses fog up horribly while riding to work. So I have the choice of either not wearing glasses and being able to see vaguely, or having completely fogged-up glasses and not being able to see at all.

What makes that more scary is that at least half the cars out there this morning didn't have any lights on at all, despite visibility being down to less than 100m most of the way. I had my bike lights on to make myself as visible as I could...
