Google has announced through a blog post that it is testing a “smart contact lens” for diabetics to monitor their blood-sugar levels while wearing the lens. The lens prototype uses a tiny wireless chip and miniaturized glucose sensor, embedded between two layers of soft contact lens material, which can generate a reading of a tear's glucose level every second. Brian Otis and Babak Parviz, the co-founders of the project, said they are exploring the integration of tiny LED lights that light up to indicate glucose levels that are either too high or too low. Parviz also leads the development team for Google Glass. The new smart lens could replace the need for people with diabetes to prick their fingers and test drops of blood throughout the day. Although discussions have already begun with the U.S. Food and Drug Administration (FDA), a lot more work still needs to be done before people can actually use the new lens, the company said. Google added in the blog post that it intends to find partners for the project “who are experts in bringing products like this to market.”
