Artificial eye lenses are frequently used to correct various vision problems, however, most are imperfect and act like glasses more than eyes. Researchers from Case Western Reserve University, Rose-Hulman Institute of Technology, US Naval Research Laboratory and PolymerPlus from Ohio have developed a new lens that incorporates thousands of stacked ultra-thin layers of polymer.  The layers work to produce a continuous refractive gradient that mimics a real human eye.
