Scientists are on the brink of restoring sight to the blind by sending moving images directly to the brain. In a world-first, surgeons have implanted a visual stimulator chip in the brain of a 30-year-old woman. The patient, who has been totally blind for seven years, saw coloured flashes, lines and spots when signals were sent to her brain from a computer.
Her 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 bypasses the eyes, meaning it has the potential to restore sight even to those who have lost an eye or become blinded by cancer. FULL REPORT
