Scientists built a bionic eye that could give blind people sight

Scientists from the US and Hong Kong have developed a synthetic eye that functions a lot like the real thing. With sensors that mimic the photoreceptors found in a human eye, the new "bionic" prototype could one day be used to restore vision in individuals that have lost their sight. Referred to as a "biomimetic eye" by the research team, the device is a marriage of modern technology and nature's own designs. It consists of a hemispherical artificial retina and an array of sensors that capture and relay a live image. Getting it to interface with a human brain is, well, pretty complicated.
