Artificial Retina
The first artificial retina has been developed / to help restore vision to people blinded by retina diseases. / This electronic device has been in human clinical trials / in the U.S. and Europe for several years. / It is essentially a sheet of tiny conductors put into the eye by surgeons. / The patient will be fitted with a pair of dark glasses / that have a small attached video camera and portable video processor. / The battery-operated system will send video signals directly to their brain. /
However, the electronic retina doesn’t restore full vision. / It only allows users to sense light and dark contrasts / and detect movement and important shapes. / And the images they perceive are not in color. / Moreover, this device can only be applied to remedy blindness caused by damaged retina. / So eventually the manufacturer hopes to put the device in the brain’s visual area. / In this way it could remedy blindness from all causes. /
解析
人造视网膜
第一个人造视网膜已经被研发出来,用以帮助因视网膜疾病而失明的人士恢复视力。这种电子设备实质上是一片微型导体,由外科医生将其植入跟内。患者会配上一副带有小型录像机以及便携录像处理器的深色眼镜。这个电池供电系统会将视像信号直接传送到他们的大脑。然而,电子视网膜只能让使用者感觉到光和暗的反差、察觉物体的移动以及重要而明显的物体形状。
