The latest advances in vision aids -- some of which could potentially help the 285 million people worldwide with some form of vision impairment -- were discussed at the American Association for the Advancement of Science annual meeting in California.
The new contact contains an extremely thin, reflective telescope, which is activated by winks and embedded inside a 1.55 millimeter-thick lens.
First released in 2013 and fine-tuned since then, the prototype was unveiled by Eric Tremblay from the Ecole Polytechnique Federale de Lausanne in Switzerland.

"We think these lenses hold a lot of promise for low vision and age-related macular degeneration," a vision disorder that affects older people, Tremblay said. "At this point this is still research, but we are hopeful it will eventually become a real option for people with AMD."
Funded by the Defense Advanced Research Projects Agency (DARPA), the lenses were meant to serve as a form of bionic vision for soldiers.
"Small mirrors within bounce light around, expanding the perceived size of objects and magnifying the view, so it's like looking through low magnification binoculars," the researchers said in a statement.
Several precision-cut pieces of plastic, aluminum mirrors and polarizing thin films form the lens, along with biologically safe glues.
