INTRODUCTION
A Bionic Eye is a device ,which acts as an artificial eye .
It is a broad term for the entire electronic system consisting of the image sensors ,processors ,radio transmitters & receivers, and the retinal chip .
Based on the institute developed these devices are developed but with minor to major differences, of these the devices with functional capability and those which are clinically tested and results proved are discussed here .
Here the designer’s objective is to go for a system that is technically perfect with no loop holes and that is harmless to the human body which receives the system and that is commercially viable both in terms of ease of manufacture ,cost and the process of implanting .
Blindness means loss of vision .Rods and Cones ,millions of the mare in the back of every healthy human eye.
They are biological solar cells in the retina that convert light to electrical impulses --impulses that travel along the optic nerve to the brain where images are formed .
Without them, eyes lose the capacity to see, and are declared blind .
The Eye
Human Eye is similar to a camera
Macula provides the highest
resolution of the image which
we see.
Macula is comprised of multiple
layers of cells which process
the initial “analog” light energy
entering the eye into “digital”
electrochemical impulses.
Human eye has nearly
100 million photoreceptors.
Need for the BIONICEYE
It has been shown that electric stimulation of retinal neuron scan produce perception of light in patients suffering from retinal degeneration.
Using this property the eye and make uses of the functional cell store in the vision with the help of electronic devices that assist this cells in performing the task of vision, we can make these lakhs of people get back their vision atleast partially .
