A man fitted with bionic eyes can see light for the first time in 30 years. From the BBC:
Ron, 73, had the experimental surgery seven months ago at London's Moorfield's eye hospital.
He says he can now follow white lines on the road, and even sort socks, using the bionic eye, known as Argus II.
It uses a camera and video processor mounted on sunglasses to send captured images wirelessly to a tiny receiver on the outside of the eye.
