Unfortunately, the Meta glasses look much more normal, and a person who isn't actively looking for them (and especially one who is unaware of them) isn't likely to notice them.
A family member has one and I didn't notice until they had to charge their pair. The little circles are subtle giveaways otherwise they look like regular pair of glasses. When everything is always on, I'd like to keep my house "off" and those things are a direct violation of that.
they are still very easy to spot. they are very bulky around the rims
There is a way to sus them out: https://www.404media.co/this-app-warns-you-if-someone-is-wea...
Not perfect, but better than nothing I guess. I don't think I've noticed the glasses IRL anywhere, but if I start seeing them, I'm definitely installing the app and avoiding any interactions with those people.
