Google testing contact lenses that monitor glucose levels
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.
