Those glasses have been used in elderly care here in Denmark for quite a while. Nurses who treat wounds use a set of glasses to document the process so they don’t have to switch in and out of gloves a million times.
I wouldn’t too much about the big American advertisement companies getting a lead on it, considering how little they are trusted outside the US in anything related to enterprise.
Those glasses I mentioned are actually Google glass if I recall correctly, but with some completely different software because naturally you can’t use Google software to document patient data in the EU.
