Blindness is more feared by the public than any other ailment. Artificial vision for the blind was once the stuff of science fiction. But now, a limited form of artificial vision is a reality. Now we are at the beginning of the end of blindness with this type of technology. In an effort to illuminate the perpetually dark world of the blind, researchers are turning to technology. They are investigating various electronic-based strategies designed to prevent various defects or missing links along the path of brain imaging and provide some form of artificial sight.
Artificial vision researchers are inspired by another device, the cochlear implant, which has successfully restored hearing to thousands of deaf people. But the human vision system is much more complicated than hearing. The eye is one of the most amazing organs of the body. Before understanding how artificial vision is created, it is important to know about the important role that the retina plays in the way we see it. Here is a simple explanation of what happens when we look at an object:
• Diffuse light from the object enters through the cornea.
• Light is projected onto the retina.
• The retina sends messages to the brain through the optic nerve.
• The brain interprets what the object is.

ARTIFICIAL VISION
The current path scientists are taking to create artificial vision was shaken in 1988 when Dr. Mark Humayun showed that a blind person could be made to see the light by stimulating the nerve ganglia behind the retina with electrical pulses that could restore the vision. Today, this device is very close to being available to the millions of people who have lost their vision of retinal disease. In fact, there are at least two silicon microchip devices being developed. The concept for both devices is similar, with each of them:
• Small enough to be implanted in the eye
• Supplied with a continuous power supply
• Biocompatible with surrounding eye tissue
