Holding a phone in front of your face in public is so normalized at this point that targeted recording is not a matter of hardware, but of someone wanting to do it.

As you point out, most influencer-types aren't aimed at you.

That generalizes pretty well, with or without glasses, no one cares about recording you, other than incidentally as part of the background

If someone does want to target recording you, i.e. you're a semi-famous idol or such, they'll just pretend to watch tiktoks on their phone and record without an indicator, right? At least the glasses have an indicator, unlike phones.

I think the angle that a phone is held at is a reliable determinant of intent. People look down at their phones to read the screen. People hold their phones up vertically to record. The difference seems immediately apparent to me.
