ARTIFICIAL EYE/ RETINAL PROSTHESIS COULD HELP THE BLIND SEE AGAIN
Artificial Eye Gaze in the shape of the natural form of human eye. Artificial eye heralds the emergence of new small-footprint devices with a wide field of view and low distortion. The resulting picture is indistinguishable from the image seen by human eye. So it will be possible to transfer the images directly into the brain of blind people with help of electronic eyeball. This development will allow to solve the problem for blind people and to make a new step in science, having opened a new direction in personal video perception systems in the field of volumetric video.
This is a completely new idea of developing a flat lens with a tiny camera that could revolutionize the eyeball. An ultra-thin flat lens focuses light without imparting the optical distortion is radically different due to a new technology development. With the help very thin silicon wafers possibly create a flat lens. Curved glass can bend the light coming from many angles in such a way that it all ends up at the same focal point, an electric sensor.
The flat lens have a series of small nano structures, arranged on the silicon wafer and when the light hits these sensors do the job of refracting the light so that it all ends up on the same focal plane. The angle at which the light is refracted depends on the shape, size, and orientation of the sensors. The sensors and the lens only focus one wavelength of light that can handle normal color images. Technology should be advanced enough to embed a tiny camera inside the lens of the eye, capable of adapting for corneal optical effects and perhaps using haptics to stabilize its position. The camera would transmit images to a nerve-stimulating chip at the back of the eye, resulting in a complete electronic vision system, translate images from camera into electrical impulses that can be understand by the nerves inside the brain.
Chip to generate a signal which is as close as possible looks like to a real retina eye. Wherever you change the input, the brain will adapt over time. If the new sort of signal is almost the way it was before, the brain can adapt really quickly. (There is for example an old experiment in which adults had to wear a sort of video glasses that turned everything upside down; so they would see the sky below them and their own feet above. Of course in the first moments this was really irritating to everybody. But within only ten days, they were even able to ride a bicycle without any problems. Brains are really, really strong at adapting.). The digital information picked up from the camera is sent to a thin film. This thin film is surgically implanted in the back of the patient’s eye. The electrical signals stimulate the nerves in the retina and that make the patient able to see.
