Earlier this year, Google took the wraps off its smart contact lens project, "built to measure glucose levels in tears via a tiny wireless chip and miniaturized glucose sensor embedded between two layers of soft contact lens material." The developer also is investigating whether integrated LED lights could show when glucose levels have passed above or below particular thresholds.
"We're in discussions with the FDA, but there's still a lot more work to do to turn this technology into a system that people can use. We're not going to do this alone: we plan to look for partners who are experts in bringing products like this to market," wrote project co-founders Brian Otis and Babak Parviz on Google's blog. "These partners will use our technology for a smart contact lens and develop apps that would make the measurements available to the wearer and their doctor."
