I've heard from a few sorces that we can now input computational images into the eye. The sources didn't go into much detail on how to do this, but I am buessing that they figured out how visual images are processed through our Optical Nerve, and - after some lengthy reasearch - were able to imitate these electrical nerve pulses and hook up a wire directly into the part of the brain which processes images.

Is this right, and if so, then why does it work? Shouldn't the patient feel some sort of electrical current flowing throught their brain? Why does the patient's brain recieve the image as if it were a normal image from out eyes?
