The human body is an expansive and complex machine with several interconnected functions, piloted primarily by the brain and energized by the flow of electricity and blood from the heart through a network of arteries and veins. The human body gathers information about the surrounding environment by means of several organs namely the eyes, ears, nose, tongue and nerves which translate sight, sound, smell, taste and touch into usable data for process by the brain. As the human body progressively ages, several of thes

“Until now those who lost their vision to retinal disease would have little hope of regaining their sight, but technical breakthroughs could soon give back the gift of sight” , thankfully emerging technology have enabled several scientists “disprove this conventional wisdom about the brain’s limited recuperative ability” . There are several technological innovations currently being enhanced by scientists in Europe, Asia and North America ranging from Visual Prosthesis to implantable chips which, as technology improves and becomes less expensive will undoubtedly make current aids for the visually impaired- Braille, the long cane and the seeing eye dog obsolete. One such technological innovation is the Dobelle Institute’s Artificial Eye, which in recent tests has enabled the blind regain rudimentary sight. Based in Zurich Switzerland, and Commack New York the Dobelle Institute has developed a visual prosthesis that in recent tests have enabled blind patients perform activities as discerning visual images and even like driving a car! The basic principle of the “Electronic Eye” or “Visual prosthesis” in its most simplistic form is to connect a television camera to the visual cortex of the brain, and then transmit digital data to the brain for processing. The “first visual prosthesis providing useful “artificial vision” to a blind volunteer by connecting a digital video camera, computer and associated electronics to the visual cortex of his brain.” , The video camera is built into a pair of sunglasses and the electrode component of the prosthesis is connected surgically to the right occipital lobe.

Output cables relay the information to a computer and then back to the brain in the form of black and white outlined images called phosphenes, similar to the light bulb arrays utilized by some sports stadium scoreboards. The system also includes a battery powered electronic interface with isolated and insulated lines for safety. The patient sees the flashes of light or phosphenes and eventually the patient can see the outline of the processed images.
