Learning to see with your tongue

Lance Bombardier, Rob Long, was blinded by an IED explosion in Afghanistan. He is the first Brit to be enrolled in a trial of a new piece of technology that could restore a sense of sight. A camera turns what it sees into 400 black and white pixels which are felt as tiny electric shocks on your tongue. After only a few hours practice, Rob gets remarkable results.
