Blindness, the final solution?

Researchers from Bar-Ilan University in Israel, developed a technology by a small camera on a bionic eye, allows people who born blind, see without any need for surgery.
According to experts, the compressed information from the camera is transmitted wirelessly to the cornea.
Hebrew Scientists explained that this new technology is a camera that receives visual information from the environment and transmits signals to a bionic contact lens.
"Lens passes signals through electrodes to the cornea and from there to the sensory areas of the brain, which creates a stimulus that mimics the visual information, "said Professor Zeev Zalevsky, director of research.
The scientist explained that the compressed information after being amplified electrically transmitted from the tiny camera by wireless. The lens will be about 10 000 small electrodes to stimulate the cornea.
«The cornea is the richest part of the eye in sensory nerves and has tens of thousands of sensory points where you can plug the small electrodes" he added.

Zalevsky also stressed that "in this way, even a person who is blind from birth, can see. In blind people develop sensory areas that receive information from the cornea, such as regions that allow them to read braille with the sense of touch.
The bionic eye is drawn up as "a braille lens that allows blind people see in a manner similar to reading in this system, he added.
I think that this technology is great news for humanity, especially since gives sight to the blind from birth without surgery or harm other senses or vital organs and brings closer the science fiction to the reality.
