I wear contact lenses and I would buy one of these without prescription glass in them. Not to use as glasses, but for the value-add. Adding features to the outdated design of the human body is a net positive as far as I'm concerned.

There aren't any with prescription glass in them. The glasses form factor is a convenient way to hide the battery in your hair.

There are/were plans to make some that would fit over existing prescription glasses, though, I think.

And to hold the glass on your face, a requirement even if there were no battery.

I wonder if he means socially accepted as in you've suddenly turned into a walking CCTV camera.

I'd feel uncomfortable if a friend brought these on a night out, but then again I think I'd be a minority here in the UK.

Don't take them to France though.
