I (and a great many other humans) already wear an accessory which sits on the face. :)

When spectacles were first invented, they may well have been obtrusive and required some social adjustment. Now they're thoroughly assimulated. They are unobtrusive, and one's choice of frames/style often serves as a fashion statement.

I wear glasses, too, but I think of it as a bug when there's something on the lens or when I talk to them. It feels like the very unobtrusiveness that makes them useful.

Maybe it's Google's habit of showing off Glass without lenses that makes me think of it as 'as screen on your face' rather than 'fancy glasses'. It reads as 'Bluetooth earpiece' more than 'hearing aid'.

Also, I kind of just want a monocle.
