I have a neurological vision disorder which I suspect augmented reality glasses would help a lot, but sod letting Meta see my life from a first-person perspective 24/7, or the lives of anyone around me for that matter. Also I suspect a genuine medical device would have to be made very obvious, you don't want accessibility tech being mistaken for pervert tech. I wouldn't take the risk frankly! It's like if I'm talking to someone and they have a hearing aid in that's fine, but if they've got headphones in I'm going to feel a little cheesed off on the face of it.

Also not American but I work for a trans-Atlantic company, those things sound like a PHI nightmare in a medical setting given Meta's habit of indiscriminately hoovering up data like as many labradors in a pantry.
