Scientists once made an experiment. They blinded the eyes of bats, and put them in a room full of bells. Bats did not hit the bells. They blocked the bat's
ears. This time, however, the bells rang. Nowadays, it is generally accepted that the sight of bats is poor, and they rely on their ears to judge the distance between things around them and themselves. We draw inspiration from the bats and design such a pair of glasses for the blind, like the invention of radars. In that case, the blind can "hear" the world.
