I think it’s reasonable if sight impaired people want to appear inconspicuous. You say this is “hiding” the glasses but do you expect them to walk around with a GoPro strapped to a helmet so they can have street signs read to them?

Man the devs founders really thought of everything.

It just sounded like the kind of thing that makes good sense on paper but I’m wondering if it actually works out well. Sounds like you are in the process of getting ready to try it.

Do you know anyone doing all of that? Running a local model on off-grid power?
