I found Oakley M-frames to be the best fit and the best at keeping wind/dirt out of my eyes. Had to stop using them because of declining vision. I have a pair of prescription Ray Bans for driving but haven't wanted to risk taking them on the bike. I found a site called Readers.com. Got some 1.75 sunglasses and they work on the bike but the frames break easily. They cost less than $20.
