I have been riding with my normal specs all summer. I would like to get a pair of RX riding/sport glasses with changeable lenses (so if it's not too sunny out I could go with a clear or at least light lense). I definitely squint on sunny days and my eyes get blinded by the pavenment halo sometimes... Shatterproof lenses would be good too.

The problem in locating such items - I have a small face and most typical shades are either super huge on me or don't take RX lenses. Any ideas? Anyone have RX ones today?

I have considered laser eye surg but I have mixed feelings about that, for example around cost (is it really worth it) and potential side effects.
