Fortunately, I only where glasses to ride for protection... not to see. My glasses are there mostly to protect my eyes from flying bees or other flying bugs. When it rains, I don't seem to see any bees or bugs so I can take the glasses off. I would find it irritating to ride with glasses and water all over the lenses. Hopefully the suggestions above solve the problem. I'm sure the day is coming when I'll have to wear glasses all the time (hopefully, that happens after the day I um unable to turn the pedals anymore.)
