I know google glass came and went but they were WAY too expensive and clunky.
However with advances if they could miniaturize a cell phone to the point where it could fit in glass frames that might be a thing.
Answer the phone by tapping your ear like a bluetooth, project the incoming number on the lens.
If you want to surf the web or use GPS project that onto the lens.
They even have that thing were you hold you phone up while you walk down the street and it shows you all the business in front of you.
