I don't think it is socially acceptable - it's like walking around with a movie camera over your shoulder where you've taped over the red LED. No-one you're talking to will know whether they're being recorded, resulting in a very uncomfortable feeling.
There's also an aspect of rudeness - when I talk to you and you're wearing these glasses I will automatically assume you're doing something different while I'm talking, which would feel very annoying. It's a little bit like the person I'm talking to is constantly staring at his/her smart phone.
If these glasses take off I can imagine explicit or implied "No Glasses"-policies at bars, and especially restaurants.
I still don't understand what they are supposed to be used for. As for the question, of course it's silly: it depends on which bar you are going to and at what time.
They are supposed to replace your bluetooth... well, also your phone... mmmm.... as a matter of fact also your notebook.... now that I think about it also your Facebook since it integrates exclusively with Google Plus... mmmm... Oh i know, they are supposed to replace real life! :D
It is acceptable if you want to look like the geekish guy in town (not to mention one of the luckiest). It is not ok if you wish to hookup, I cannot image a pickup line that starts... "hey Pamela, I did a reserve google image search of your face and found out that you use pretty neat lingerie" :/
