Here, we present a description of a block scheme, specific features of design
and results of testing for a prototype of a bionic eye, types of them and its applications. The bionic eye is intended to provide vision, partially to the visually impaired by use of the modern day electronics devices like CCD cameras. The comprises a computer chip that sits in the back of the individual's eye, linked up to a mini video camera built into glasses that they wear. Images captured by the camera are beamed to the chip, which translates them into impulses that the brain can interpret. Although the images produced by the artificial eye were far from perfect, they could be clear enough to allow someone who is otherwise blind to recognize faces. The paper discusses the differences working methodologies used in each . During the tests and the clinical trails, this device made six blind people to regain their vision partially. The potential advantage of using bionic eye is to be able remove the blindness completely by making the advances in the present research and improving manufacturing technologies. This break through is likely to benefit approximately one core world population who suffer from the most common causes of blindness, Retinitis Pimentos, Macular Degeneration. The implant bypasses the diseased cells in the retina and stimulates the remaining viable cells. This is a piece of technology and really has the potential to change people's lives. But we need to be aware it is still some way in the future.
