A recent article in New Scientist highlights several different emerging technologies that incorporate microelectronics into contact lenses. But these devices aren't designed for vision correction. Rather, scientists at the University of Washington in Seattle, for example, built on their previous development of an LED-equipped contact lens to create a glucose monitor-on-a-lens device for diabetics. Using tiny electrodes and a computer chip, the lens can monitor glucose levels in tears to avoid painful finger thumb pricks. Data collected could be transmitted wirelessly.
