Electrodes on the artificial retina will stimulate the optic nerve of the retina, and continue to send signals along the optic nerve to the patient’s brain, these impulse signals can “deceive” the patient’s brain, so that the brain thinks that the patient’s eyes are still in a normal working condition, and eventually the patient can be the same as a normal person, “see Eventually, the patient can “see” the outside world as a normal person and distinguish between light and darkness, thus restoring his or her vision.
