Not sure what to make of that. I'd hate to think that people around me had these things in their specs (I absolutely detested the Google Glass thing)... how intrusive would that be? However, better images of the universe... I like that.
No more different or disruptive when Google Glass was in play. Our sensibilities, privacy thresholds and social conduct expectations will change over time - and it needs to change as fast as the technology - otherwise we will be looking at a modern day burning of the Weaving Machine. Legislation and Court comprehension of certain technology segments are particularly, painfully behind the times.
The Millennials have a completely different concept of privacy, ownership and discretion to the Perennials. All of us posting here are in the latter camp and find their behaviour inexplicable and often distasteful or disrespectful.
