Randy Atkins:  Blind people might one day wear glasses with small cameras — the images placed directly in their brain's healthy vision pathway through an implanted electrode.

John Pezaris:  It's not just as simple as putting a bunch of wires all together, there's a little bit more engineering that needs to be done.

Randy Atkins:  But John Pezaris, a Harvard Medical Center engineer, says animals are already seeing points of light with the eye bypass.

John Pezaris:  For a real visual prosthesis, that is something that a person could use to walk around, to recognize objects or people, to be able to perhaps read signs, you’d need many more than one or two pixels.

Randy Atkins:  He's confident further work will bring such complex images into the brain too.  With the National Academy of Engineering, Randy Atkins, WTOP Radio.
