This may have been covered in an old thread, but I couldn't find anything on it. Am wondering what the bespectacled cyclist does to keep the rain from making the trip treacherous. Raining hard today on the way home and went to look over my left shoulder for oncoming traffic before I put the old left turn signal out there and was quite surprised to find I couldn't see! Or hear since it was raining so hard. (Took the recommended option of pulling off the road and did the old finger-as-windshield-wiper routine.) I heard of RainX for cars and an antifog spray for glasses, but wondered if there's something tried and true to repel rain from glasses. (I don't really want to wear anything more over my glasses either.) I also don't want to ruin my glasses. Ideas?
