Eye LightsHere’s something to make your twinkle, or water…. Researchers at the of developed contact lenses with embedded light emitting diodes LEDs and driver circuits just a few nanometers thick. The idea is eventually it could be formed into a ‘heads up’ display for a or , night vision system or even an aid for the visually impaired. At the moment the prototypes can do nothing very useful, just a few blobs of light that flash on and off. A means of getting power to the chips in the also needs to be figured out, the idea of a couple of wires going onto your eyeball doesn’t bear thinking about, but it should be do-able, using electromagnetic induction or solar power; we’ll just have to wait and see where this one is headed…
