SCIENCE WILL ONE DAY CURE BLINDNESS

ABOUT 170 000 VEHICLES USE NEW YORK CITY’S QUEENSBORO Bridge each day, zooming past Larry Misrok’s apartment building, which sits at the entrance to one of the ramps. Crossing the street there is challenging for anyone, but for Larry, an 83-year-old lawyer, it could be deadly. He is virtually blind.

Fortunately, Larry has help to navigate the city’s busy streets and broken sidewalks: A healthy pair of eyes with 20/20 vision located hundreds, maybe even thousands, of miles away. Using high-tech, camera-equipped eyeglasses, along with an app on his smartphone, Larry is guided by a trained agent who can see in real time on his or her computer screen what Larry cannot see before him.

‘Watch out, there’s a curb ahead,’ the helper might say, or ‘There’s a cyclist coming up on your right.’ It’s like having a friend at his side when the environment is too dangerous or too challenging to be guided by a cane only, the traditional way the vision-impaired navigate the world. Obvious safety benefits aside, this innovative tool, called Aira, is also useful for assisting with grocery shopping, selecting cafeteria items, choosing clothing, operating office equipment, sorting mail, interpreting slide presentations, and other tasks that are difficult or impossible for people with low vision. A quick call puts Larry in contact with one of hundreds of paid Aira agents located around the country who are standing by to commandeer the camera on his glasses and narrate his surroundings.

The Aira system is
