Google Unveils Smart Contact Lens Project to Monitor Glucose

Google Inc. is diversifying into contacts lenses -- smart ones.

The Mountain View, California-based company said in a blog post yesterday that it’s testing an ocular device that’s designed to measure glucose levels in tears, as the company pursues long-term projects at its secretive X Lab research group. The lenses use a tiny wireless chip and glucose sensor to provide readings once per second, project co-founders Brian Otis and Babak Parviz wrote in the post.
