This device is sometimes referred to as the bionic eye since it is an impressive and revolutionary piece of technology that can make people who have lost their eyesight see again. First, “a tiny retinal implant is put into the human eye, and then later, a gadget is put onto the human body. With the small retinal implant, it receives radio messages and transfers these messages to the brain through the optic nerve. The device acts as a stimulator, in which it is set up at any position in the visual pathway to electrically stimulate neurons and retinal cells” (Ranjakumar, Rahana, and Lalith, 2016). Basically the device must be on, and worn at all times in order to stimulate those retinal cells and neurons in able to produce the visual sights these people are looking at. In our history, there have been a few types of artificial retina device that have been developed and tested in
