Photo: "Bionic" Contact Lens May Create Tiny Personal Displays



A new contact lens embedded with nano-size electronic circuits could be the first step toward "bionic eyes" that allow users to see tiny but discernable readouts over their normal vision, researchers say.

Although the circuits are not yet functional, the lenses are flexible and biologically safe, the team notes. Lab rabbits fitted with prototype lenses, like the one pictured above, showed no adverse effects after about 20 minutes of wear.
