World's first bionic eye gives the blind a chance to see again
Scientists are working on the possibility of restoring sight to the blind by sending moving images directly to the brain.
Surgeons have implanted a visual stimulator chip in the brain of a 30-year-old woman who has been totally blind for seven years.
After the chip was put, she could see coloured flashes, lines and spots when signals were sent to her brain from a computer.
Doctors are now planning to send footage from a tiny video camera to the brain, which could provide the world's first bionic eye and restore sight to millions.
The technology might be able to restore sight even to those who have lost an eye or become blinded by cancer.
