According to Google, the sensor in this contact lens can take about one reading per second, and it is working on adding tiny LED lights to the lens to warn users when their glucose levels cross certain thresholds. The sensors are so small that they ”look like bits of glitter.”
Google says it is working with the FDA to turn these prototypes into real products and that it is working with experts to bring this technology to market. These partners, the company says, “will use our technology for a smart contact lens and develop apps that would make the measurements available to the wearer and their doctor.”
It’s worth noting that other companies, including Microsoft, have previously shown similar lenses. Until now, though, it doesn’t look like there are any smart lenses available in the U.S. yet. Given Google’s reach, however, it may just be able to find the right partners to bring this technology to market.
