Scientists 3D-print a 'bionic eye' that could soon let blind people see again

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.”
