If you have diabetes you may soon be able to stop pricking your fingers.
Checking your blood sugar could be as easy as a new pair of contact lenses.
At first glance it looks just like a regular contact lens, but researchers at the "Google X" Lab say it can do a lot more than just improve your vision.
This prototype contains tens of thousands of tiny transistors that are designed to sense glucose.
It's just one of several medical devices researchers are working on to help diabetes patients.
Google X Engineer Brian Otis says, "We're testing a smart contact lens that we built that measures the glucose levels in tears using a tiny wireless chip and a miniaturized glucose sensor."
Researchers hope to have the new contacts ready for consumers in about five years.
