This free app is for two kinds of people: Blind folks, and sighted folks who want to help them. If a blind person needs help identifying something—say, the “sell by” date on a carton of milk—they can start up a live audio-visual connection and aim the iPhone’s camera at the object they need help with. Sighted folks—volunteers who download the app—will be alerted that help is needed, open Be My Eyes on their iPhone, and see what the camera’s aimed at. Then they can answer the blind person’s question. It’s a pretty incredible app, with a great purpose.
