Specialized goggles that send information to solar cell–like chips implanted in the eyes may one day help some blind people see. The new implants, which have been tested in rat retinas in a dish, would require less invasive surgery than similar devices now being tested and offer a higher-resolution view of the world.

The new system, reported online May 13 in Nature Photonics, still needs work before being tested in people. But one day it may return partial sight to people suffering from con...
