Augmented Reality in a Contact Lens
A new generation of contact lenses built with very small circuits and LEDs promises bionic eyesight
The prototype device contains an electric circuit as well as red light-emitting diodes for a display, though it does not yet light up. The lenses were tested on rabbits for up to 20 minutes and the animals showed no adverse effects.
Ideally, installing or removing the bionic eye would be as easy as popping a contact lens in or out, and once installed the wearer would barely know the gadget was there.
The prototype contact lens does not correct the wearer's vision, but the technique could be used on a corrective lens.
