This video is a snippet of a documentary entitled, “The Boy Who Sees Without Eyes about Ben Underwood a young man that developed Bilateral Retinoblastoma (cancer in both eyes). “Ben Underwood lost his eyesight at the tragic age of three to retinal cancer. But despite his handicap, he shoots basketball hoops, zooms around on a skateboard, and can weave between lampposts and parked cars without any help. Incredibly, Ben has a developed an extraordinary sound technique to help him see. Like bats and dolphins, he clicks to ‘see’ his surroundings – a process known as echolocation.
