I can't think of one single practical use case for this that would benefit my life, because, right behind the glasses I have my very own locally available facial recognition built in.
A lot of people are face blind (including me), and it's extremely embarrassing, especially when I'm supposed to remember a person's name. Wouldn't wear survialiance tech to try to fix it though.
I'm great at recognizing faces, but I'm pretty bad at remembering who they are. If this was offline only and the UX was reasonable, I might consider asking people I know if I can take their picture so my glasses can help me remember who they are. Of course, that's a pretty awkward conversation, so there's always the strategy of half introductions, hoping the people you half introduced fully introduce themselves and then you remember who they are. :P

I’m not diagnosed face blind but I’m hoooooorble with names. It’s weird because I’ve been tested and score in the 98th percentile for memory generally.
I hung out with a large group of people for nearly a decade and couldn’t remember who was who until the pandemic. The names under zoom helped me gradually learn over weeks.
When I teach scuba I recite the list of student names for my class in as random an order as possible while I drive to the shop to lower my cognitive load to put faces to names. When I do roll call, I write down every person’s name and try to gradually move off the cheat sheet as I call on them to answer questions. But once they put on their gear (especially since I teach where they use hoods) it all goes downhill. Two white guys approximately 35yo? I’ll get them confused.
If this were socially appropriate I’d totally use it as my prescription glasses to help continue smoothing the curve.
