Scientists Reveal a Proof-of-Concept Bionic Human Eye - ScienceAlert

The nanowires are so sensitive they could surpass the optical wavelength range of the human eye, allowing it to respond to 800 nanometer wavelengths, the threshold between visual light and infrared radiation.

"A human user of the artificial eye will gain night vision capability," Fan told Inverse.

Each square centimeter of the artificial retina can hold about 460 million nanosize sensors, dwarfing the estimated 10 million cells in the human retina.
