A contact lens which contains a glucose sensor, an antenna, a capacitor and a chip has been developed by Google dedicated to people suffering from diabetes. It does not restrict eyesight and performs analysis of glucose twice every second, afterwards send the information gathered to an external monitoring device with the help of radio waves.
Having 1 in 19 people on the planet dealing with diabetes, it can become like a part-time job to manage. Glucose levels change frequently throughout the day and a close eye must be kept on readings at all times through blood drop tests and other methods. The Google team tasked with the project came up with the contact lens idea, which is made out of chips and sensors that look like bits of glitter and an antenna that is thinner than a human hair. They also overcome the battery issue with the help of radio waves, which provides the necessary electrical energy necessary to power up the sensors inside the lens.
It is said that future models may even include a light source built into the lens that would let wearers know the status of their glucose levels without having to look at the external monitoring device, according to project lead Brian Otis, which can be activated via a blinking feature or the user closing his or her eyes.
Google is currently in talks with the FDA, but they say there is still some more work to be done on it until we see one of these lenses on the market.
