> I bet most people won't know what is going on even if they notice the eyeglasses have an LED that's on. It's not like an LED is a universal signal for "your privacy is cancelled now". On decoy surveillance cameras they'll usually have a blinking or solid LED on them because the trope of "blinking red LED means it's recording" is so widespread. That's been used in film, self checkouts, body cameras, surveillance systems, etc. I don't know what indication would be more likely to signal a recording in progress short of a loudspeaker screaming "YOU ARE BEING RECORDED RIGHT NOW". I think it's far more likely that the general public will be unaware of the existing ways they are being surveilled.
