It’s a staple feature in many science fiction blockbusters, and now scientists have developed a fully 3D printed bionic eye for the first time.
Researchers from the University of Minnesota printed an array of light receptors on a hemispherical surface.
And they believe that the bionic eye could soon let blind people see, or sighted see better.
Dr Michael McAlpine, co-author of the study, said: “Bionic eyes are usually thought of as science fiction, but now we are closer than ever using a multimaterial 3D printer.”
