This is one of the coolest inventions I've seen recently. Researchers at the University of Washington have implanted electronic circuits and LEDs into contact lenses. Energy is transmitted wirelessly to the lens, lighting up the LEDs. Still in very early experimental stages, the applications are endless. From video game players to airline pilots to anesthesiologists, anyone who has to look at a computer screen for an extended period of time would find this useful. It's like a heads-up display you find in some car models, where you don't have to turn your head to find important information. Reminds me of science fiction movies like Terminator, where the robot's eyes view complex graphs and numbers while staring down the victim.
