A device mounted onto eyeglasses enables people considered legally blind to "read" and perform other day-to-day activities, according to researchers.
The device, called OrCam, features a miniature camera with optical character-recognition technology. The camera deciphers text and then "reads" it to the user through an earpiece. The device can even be programmed to recognize specific faces and commercial products, according to the report.
"It is easily used and could potentially bring greater independence, particularly for older patients who are struggling with vision lossHis team's pilot study included 12 people, average age 62, with severe vision loss caused by a variety of disorders. All were legally blind. The participants were first trained how to use the device, which operates either by tapping it, pressing a trigger button, or pointing it at an item.
After one week using OrCam, all participants could perform nine of 10 tasks, including: reading a message on an electronic device such as a smartphone or tablet, a newspaper article, menu, letter or page from a book; recognizing paper money denominations; locating a room in a hallway using wall-mounted signs; and recognizing products and distinguishing between similarly shaped and sized cereal boxes.
Only one person had technical difficulties with the device. Overall, the participants said the device was simple and easy to use and they would consider using it in their daily lives.
OrCam could benefit people with age-related macular degeneration or advanced-stage glaucoma, two of the leading causes of vision loss among older Americans, Mannis said.
Two experts unconnected to the new study agreed.
While "more research is warranted . . . advancement in this technology could eventually make visually impaired individuals more independent," said Dr. Nazanin Barzideh. She is chief of vitreoretinal surgery at Winthrop-University in Mineola, N.Y.
Dr. Mark Fromer is an ophthalmologist at Lenox Hill Hospital in New York City. He noted that most instruments that currently help people with low vision are simply "magnifying" devices.
The OrCam works in a different way. "This small pilot study demonstrates that portable artificial vision devices may be an effective aid to the visually impaired," Dr. Fromer said.
He believes the technology "deserves further exploration, to aid the millions of individuals severely limited by their visual status."
