Google has invented a new smart contact lens that measures glucose levels in tears using a tiny wireless chip and miniature glucose sensor, a device that could potentially be incredibly useful for people with diabetes. Prototypes are currently being tested to record readings once every second, with plans to research the ability of using the device to serve as an early warning signal. Glucose levels in people with diabetes change so frequently, round-the-clock monitoring is required. A device like this could be very useful and maybe even save lives.
Development continues and discussions with the FDA are currently being held, but Google confirms that there is still much work to be done before people can take advantage of this product.
