Google Smart Contact Lens

While the general public tries to wrap their head around Google Glass, the company unveiled Thursday (Jan. 16) a smart contact lens that monitors glucose levels in tears to help diabetics monitor their blood sugar levels.

According to the
AP, the prototype is one of several medical devices being designed by companies to make glucose monitoring for diabetic patients more convenient and less invasive. The contact lens, however, is at least five years away from release, says Google.

It uses a minuscule glucose sensor and a wireless transmitter to help diabetics, who need insulin, to keep a close watch on their blood sugar and adjust their doses.
