Rajat Bhageria (far left), Ben Sandler (second from right) and Joe Cappadona (far right) came up with a solution during the PennApps hackathon: a Google Glass image-recognition app called ThirdEye that verbally identifies objects for people who can't see.

A search is now on for investors to help manufacture and distribute it.
