Just so you don't think everything was perfect with these glasses, I did run into a couple of issues once I started using them more regularly. From my previous posting you know that the Rx insert got off to a very rocky start. But once that was resolved there's just been some minor things, like one of the hinges has always been a little stiff (harder to open and close one ear piece compared to the other) and it's been working the screw out of that hinge. So I have to re-tighten it occasionally. The other issue is keeping them clean, I have to removing the Rx insert after almost every ride in order to clean the Rx insert lens and the photochromic lens separately.
