I get mine from the optometrist. Polycarbonate with scratch resistance.

Same here. I have a quite strong astignatism prescription myself. In order to get into wrap-around lenses - which I think is important on the bike - we actually had to cut back a bit on my prescription. There was an adjustment period when I would go between glasses, but once my eyes became accustomed to the change I stopped even noticing it. I won't use those glasses for anything outside of riding or driving - AND they don't have a bifocal...it was the solution that worked for me. My prescription can vary quite a lot from year to year, both directions, so am hoping it will be less complicated next time.
