10．Ben Underwood is blind．Both eyes were removed when he was just three years old，leaving him with no vision at all．So how on earth does he ride his bicycle，play football and basketball？
Ben uses many common aids for the blind，like speaking software．He's also written a book and does his schoolwork on a hi-tech Braille writer．But what's unusual is what he doesn't use．Ben has no guide dog and never uses a white cane．He doesn't even use his hands．Instead，he sees with sound．Amazingly，Ben's ears pick up the echoes（回声）and he can precisely locate where things are．Ben is the only person in the world who sees using nothing but echolocation．
Ben was born perfectly healthy，with dark eyes like his mum．But，when he was two she looked into his eyes and saw something was terribly wrong．This is a rare infant eye cancer that affects only one in every six million．In an attempt to save his sight，doctors immediately began intense chemo and radio therapy，but like a lead balloon．His eyes had been removed．
Just one year after the operation to remove his eyes，in the car he asked his mum what the big building was that they were passing．Ben's ears were picking up the sounds of the city traffic reflecting from the building's surfaces．His mum let him play in the street because his sound pictures seemed to make him more aware of danger than his sighted friends．
There's nothing his friends can do that Ben Underwood won't attempt and conquer．Doctors suspect that Ben Underwood has developed super-hearing to make for his loss of sight．However，tests show that he has only normal hearing．So，has Ben's brain learned to translate the sound he hears into visual information？
