(CNN) - Google is working on a contact lens that could help diabetics, but it's still in the early stages.
Google said it could measure glucose in your tears using a wireless chip and a tiny sensor.
The electronics in the lens are so small that they appear to be specks of glitter, Google said. The wireless antenna is thinner than a human hair.
If successful, Google's newest venture could help to eliminate one of the most painful and intrusive daily routines of diabetics.
The company said it would be an alternative to having to prick your finger to do a blood test.
Google has run clinical research studies, and the company is in discussions with the U.S. Food and Drug Administration.
