Google is always up to something, and their latest dally into the tech space with their Smart Contact Lens proves that they’re not slowing down any time soon. Google is starting to become known for their products that slightly (or explicitly) blur the lines between tech and the human body and the way we live. Take their latest acquisition of Nest, which sees the giant moving into our homes to improve productivity and even comfort. Google’s new Smart Lens Project aims to follow suit.

What makes this project so unique is its goal to help those with diabetes to better manage the disease. One out of every 19 people on the planet has diabetes, and when uncontrolled it can lead to other serious health problems. Google has taken the challenge of finding a better way to manage diabetes with a person’s tears. Yes, tears. They’re increasingly becoming a better way to measure glucose levels. Google’s smart contact lens prototypes are made with a network of miniature chips and sensors that are the size of a speck of glitter.

The Smart Lens prototypes are currently under testing. Right now, they’re able to produce a reading every second, and feature microscopic LED lights that can indicate when glucose levels have crossed above or below certain thresholds.

While there’s a lot more to do, Google is definitely moving in the right direction with a smart design solution for an age-old problem.
