Phones already make people much more reserved and less "wild" eg at parties compared to pre-phone-cameras (that are always online and can upload to social media effortlessly).
It's true but phones are much more obvious that you have them out and probably filming where the glasses aren't so can be more controlled and at least reacted to. The glasses create more uncertainty about if the person is filming.
It's more obvious, but since people use their phones all the time anyway, you really have to look at the angle they hold the phone to be sure. So it's not super hard to be sneaky about it even with a phone.
Most people are pretty obvious about it if you're looking. It's still the fact they could be doing it right in front of you without you knowing that really makes people hate the subtle-camera-on-face-products.
True, though there's a lot of parties that now ban phones or put stickers on them.
I've found being over 40 has made me way less wild at parties.
