A synthetic, soft tissue retina developed by researchers at the University of Oxford, UK, could offer fresh hope to visually impaired people. Until now, all artificial retinal research has used only rigid, hard materials. A light-activatable 4 x 4 droplet array. Image credit: Restrepo Schild et al, doi: 10.1038/srep46585. Just as photography depends on camera pixels reacting to light, vision relies on the retina performing the same function. The...
