This artificial retina doesn't just aim to restore sight—it opens a hidden channel of vision

The retina, the thin layer of tissue at the back of the eye, is made up of photoreceptor cells that convert visible light into electrical signals, which is essential for human vision. Some diseases, such as retinal degeneration, cause these photoreceptor cells to stop working, which results in blindness. Researchers at Yonsei University, the Institute for Basic Science (IBS) and other institutes in the Republic of Korea have recently developed a new artificial retina that could partly restore vision in people with damaged retinas.
