Google has begun testing on an intelligent contact lens that’s built to help control diabetes – a disease affecting one in every 19 people on the planet – by measuring glucose levels with mini embedded electronics.

Developed by Brian Otis and Babak Parviz, the project uses a tiny wireless chip and miniaturized glucose sensor embedded between two layers of soft contact lens material.

As glucose levels change frequently with normal activity like exercising or eating or even sweating, the concept aims to continuously monitor body fluids such as tears instead of blood drops, which require users to prick themselves for samples throughout the day.
