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.
I still see folks wearing Wayfarers almost every single day, and have owned various (non-Meta) pairs of them for most of my adult life. It's literally one of the most popular sunglasses designs of all time.
