Why bionic eye

In this a video camera is integrated with a pair of glasses which will capture and process images. The images are wirelessly sent to small processor which converts it into electronic signal and these signal further transmitted to a retinal implant or electrode which send visual signal to brain for further processing. So by this even blind people also have vision. When a light ray reflected from an object an reaches to our eye then signals are sent to brain then brain decodes the signal in order to optimize the appearance, location and movements of the object we are seeing at.

The whole process is performed due to light only, without light there is no world which means we are not able to see anything. The main part of an eye is retina. The retina is an inside wall of eye which works as film of a camera to capture the light signals and transmit them to brain via optic nerves to create vision.

It consist of electronic systems having image sensors, microprocessors, receivers, radio transmitters and retinal chips. Technology provided by this help the blind people to get vision again. It consist of a computer chip which is kept in the back of effected person eye and linked with a mini video camera built into glasses that they wear.

Then an image captured by the camera are focused to the chip which converts it into electronic signal that brain can interpret. In the miniseries Cosmos , cosmologist Neil de Grasse Tyson explained the evolution of the human eye as a direct consequence of our origins in the sea. The same way we put on sunglasses against the bright sun, primordial bacteria sunk into the sea to avoid damaging UV light. Now, an imitation eye packed with million custom-generated nanowires could take human vision forward at last.

But different scientists' methods for achieving this vary. What's more, bionic eye technology is still in its infancy compared with cochlear implants for hearing loss. Several bionic eye implants are in development, but currently only one is available in the United States, and it is suitable only for blindness caused by specific eye diseases. However, as research continues, more and more people may soon benefit from high-tech bionic eyes.

A bionic eye is not the same thing as a prosthetic eye. Prosthetic eyes also called "glass eyes" or "artificial eyes" replace the physical structure and appearance of an eye that must be removed due to trauma, pain, disfigurement or disease. Bionic eye implants, on the other hand, work inside the existing eye structures or in the brain. They are designed to achieve functional vision goals — as opposed to physical, cosmetic ones.

The Argus II Retinal Prosthesis System consists of a tiny eyeglasses-mounted camera and a transmitter that wirelessly sends signals to an electrode array that is implanted onto the damaged retina of a blind person.

Just as there is no single cause for blindness, there's likewise no one cure. To determine whether a bionic eye could help you see, it's important to know the reason s for your vision loss. The process of sight begins when light enters the eye.
