A soldier blinded in battle has become the first member of the armed forces to test a special pair of glasses which allow him to 'see' using his tongue.

Lance Corporal Craig Lundberg, who was blinded in a grenade attack in Basra, is trying the glasses which turn pictures into electrical impulses that are felt on the tongue.

The different sensations mean he can distinguish between light and dark and negotiate his way around objects.
