The Attorney General's warning is grabbing headlines, but framing this as a smartglasses problem specifically might be missing the point - phones with cameras have been capable of the same covert recording forever, and they're way more prevalent. That said, yeah, the hands-free aspect and the form factor do make it easier to hide what you're doing, so there's legitimate reason to think about it differently than a phone someone's holding.
The practical angle most people skip is learning what your local recording consent laws actually say. Some places require two-party consent (everyone being recorded needs to know and agree), others just one. Know which you live under, because that changes whether covert smartglass recording is just creepy or actually illegal. Then, if you're in a space where you're concerned - changing rooms, bathrooms, anywhere private - you have grounds to ask someone to remove them or call it out without just sounding paranoid.
Beyond that, the enforcement side is where things get fuzzy. Laws exist in most places, but prosecuting someone for recording on smartglasses is harder than prosecuting phone recording because it looks so innocent. Your real protection isn't legislation catching up (which moves slow) but awareness - people knowing these devices exist and being willing to say something when they see them in inappropriate places. Communities that normalized calling out covert phone recording five years ago will adapt faster to smartglasses too.
