Refugee camps are usually seen as scenes of crisis. But a team of innovators wants to change that.
Ahmad's world went dark at age 22 when he was shot across the eyes during the Syrian civil war.
But two years later, a Syrian refugee named Asem came across a startup called Refugee Open Ware, where he learned to build Ahmad a customized echolocation device that fit over his hand.
The device uses vibrations to indicate how close objects are in his environment, and it's helping Ahmad walk on his own again.
