An anonymous reader writes "Restoring hearing with cochlea implants that replace the inner ear with an electronic version has become standard procedure for many types of deafness. Now it looks like the same thing might happen for many types of blindness. With five national labs funded by the Department of Energy, this third-generation artificial retina promises to enable the blind to see again soon. Already it has been successful in over a dozen test patients, but at resolutions too low for doing much more than proving the concept. However, if the DoE can perfect this larger version of an artificial retina, then the company Second Sight promises to commercialize the implant, aiming for VGA resolution within the decade."
