Anybody know if the lenses from the non-RX version of these glasses will fit into the RX frame? I've got a pair of them with mint lenses but a buggered frame and there are a few RX frames on ebay right now. But can I swap the lenses into an RX frame?

Christian, just tried the leather gold in a pair of RX and they fit fine.

Thanks!

They're both base 4 frames - actually, just exactly the same frames, I think - so it shouldn't be a problem.

be careful though, because the OO Square Wires came in two lens sizes. IIRC, my Leather Gold one and my OO +Red pairs are 49-19 and my Grey pair is 47-19.

Bong, what do those numbers mean?

the 47 or 49 is the size (width) of the orbital, and the 19 is the length of the bridge.

Thanks! Were there any other models that came in different sizes?
