The smart contact lens carries tiny wireless chip and obviously a tiny glucose sensor, both built-in between two thin contact lenses. The prototype is able to take the readings of glucose levels in tears once per second. They are also considering the potential for the smart lens to become an early warning for the patient wearing it, by embeding miniature LED lights that would light up when glucose levels reach the certain levels.
Google is already in talks with the FDA about the possibilities of bringing the technology to the people but there is still a lot of work to be done.
"We plan to look for partners who are experts in bringing products like this to market. These partners will use our technology for a smart contact lens and develop apps that would make the measurements available to the wearer and their doctor", as Brian Otis and Babak Parviz, project co-founders posted on Google's Blog.
