I believe regulations in Japan currently prevent disabling the camera shutter sound in order to combat privacy invading photos being taken, so this still happens in some places.

Of course, those devices aren't made by a company whose sole purpose is the total and utter destruction of privacy, which is where this idea perhaps breaks down for the Ray-Bans.

I'm not sure the opposition is based on the company behind them.

Camera phones are probably accepted because you only pull it out when you can feel for the consent wherever it seems you're about to point the thing. With camera glasses, you're always pointing it right at the face of everyone you talk to.

I imagine if someone entered an establishment with their camera phone out recording everything all the time, they'd likely be told to put it away or get kicked out, too.
