\"The researchers used a custom-built 3D printer to construct their bionic eye prototype. First, they printed a base of silver particles on the inside of a hemispherical glass dome. Next, they used semiconducting polymer materials to print photodiodes, devices that convert light into electric signals, on top of the silver base.\
\
The entire process took about an hour, after which the team had a bionic eye that could convert light into electricity with 25 percent efficiency (safe to say that's less than our natural eyes can do, since they can detect a single photon).\"\
