This pair of glasses, called MyDo Bururu, prevents the wearer from falling asleep. Designed to assist those cramming for exams or going on a long drive, they work by detecting what angle the bespectacled user’s head is at. If the head drops below a certain level, a little motor kicks-off to vibrate the earpiece and no doubt scare the crap out of whoever is wearing them. The glasses can be set to go off at one of four levels of head-droop.
