I wasn't arguing for or against the glasses specifically. We actually had a post about those a week or so ago. I'm just pointing out that 'privacy' is a dumb argument to hang your position on. In public, there is no such thing and hasn't been for years (decades).
Those CCTV cameras, dashcams, just randoms filming stuff on the street are all around you. Yes, security and safety are the reasons most of the cameras film everything in front of them. But you do something stupid or funny enough, and that footage is suddenly posted online. You have no agency. You have no recourse to have the footage removed.
If you are out in public, just assume you're on camera. Because odds are decent that you are.
