I'm sure, I was at least not picking polycarbonate glasses for reason they look, and feel too toyish, and too many of them would be scratched in transit/pop out of frames unless overmolded.

For the same reason, I did not risk buying plastic frames. They break/bend too easily.

I'm still amazed that Chinese factories managed to make optical grade glass, cut, and polished for glasses almost as cheap as molded polycarbonate.
