福克斯新闻 用仿生学的眼睛看世界 Bionic Eye（在线收听）

A new high-tech procedure is giving blind patients their sight. After FDA approval last year, four people in the U.S. have undergone surgical implantation of a 'bionic eye.' The artificial retina system includes a small video camera and a transmitter within a pair of glasses. Camera images are converted into electrical pulses that transmit to the retina, relaying the signal to the optic nerve. The medical community is calling the device a total game changer.
