We have been detailing the progress of advances in artificial vision. Past advances consisted of the successful implantation of arrays of electrodes, which took the place of dead rods and cones and could stimulate the optic nerve to "see" patterns. Such efforts could be seen as a stepping stone to what these researchers hope to accomplish. The University of Illinois and Northwestern University have taken artificial vision to the next level by designing a fully artificial eyeball, which cou...
