Looks like Novartis owned Alcon saw something promising in Google's lens technology.
From New York Times: Joe Jimenez, the chief executive of Novartis, acknowledged in an interview that many previous attempts to develop noninvasive glucose tests had failed, noting that the company previously tried — and failed — to develop its own glucose-monitoring contact lenses several years ago.
What makes this case different is the involvement of Google’s engineers, he said. “One of the biggest hurdles was miniaturization, and that’s one of the biggest benefits that Google X brings,” he said. “This is a set of engineers that are really doing incredible things with technology.”
While the glucose-monitoring lens has gotten most of the attention, Mr. Jimenez said he was also encouraged by another lens in development that would work much like autofocus on a camera, by helping the eye focus on near objects, then readjusting when the user looks at something far away. He said that product was not as far along in development, and that both lenses were still early in their development.
