Wi-Fi eye lens

    There are caveats, of course: The single-pixel contact lens display, because of its tiny antenna, has to have a power source within 10cm. This problem could be overcome with a battery pack hooked over your ear, though (or if you’re a hardcore trans-humanist, embedded into your scalp or spine). The other issue is that this is just a single pixel — but even there, you can imagine military uses (“missile lock!”) or perhaps just as a custom notification (“you have email!”)

     Niggles aside, this invention is significant because the rabbit was alive, and no damage to the rabbit’s eye was found after the lens was removed. The research team have already drawn up plans to project multiple pixels onto a single contact lens by using an array of micro-Fresnel lenses, too (see main image). The point is, our grasp of semiconductors and optics is now so advanced that we can shrink all of the necessary components for a computer display into a contact lens. Bionic vision really is just around the corner now.
