They have been super…and yes, I actually stopped wearing my glasses in my O+ because I was worried about scratching my lenses. I just jammed my Oculus Rift WidmoVR lenses into my O+ (they rest in there, but not precisely) but I have the actual O+ lenses on the way.

They do ship from Poland, so they may take a few days to get through customs, but they arrived in pretty short order (a couple weeks).
