These glasses help the blind borrow eyesight
A company in California called Aira has created smart glasses that let blind users borrow the eyesight of those who can see.
Aira headsets consist of Google Glasses that beam a blind user's field of vision to a remote Aira agent, who then describes the user's environment through smartphone-connected earbuds.
So far, 400 subscribers have used the paid service for help with regular tasks like reading a menu at a restaurant, moving around a grocery store, or checking the expiration date on food in the fridge.
One user relied on Aira for help in running the Boston Marathon. Aira plans to use these glasses to help clients with sensitive situations, like doing finances or using the bathroom.
