Google testing contact lenses that monitor glucose levels

This undated photo released by Google shows a contact lens Google is testing to explore tear glucose. After years of scalding soldering hair-thin wires to miniaturize electronics, Brian Otis, Google X project lead, has burned his fingertips so often that he can no longer feel the tiny chips he made from scratch in Google's Silicon Valley headquarters, a small price to pay for what he says is the smallest wireless glucose sensor that has ever been made.

Google is working on contact lenses that may be able to monitor glucose levels in tears.

Google says the contact lenses could measure glucose in your tears using a wireless chip and a tiny sensor. The company says it would be an alternative to having to prick your finger to do a blood test.

The tech giant says the project is still in the early stages and is still five years away from being available to the public.
