Google's next moonshot is a contact lens for diabetics
While the actual technology is interesting in this announcement, the first thing that we noticed is that the announcement is from Google and makes no mention at all of the health/biotech company that Larry Page recently announced, Calico. Calico has been tasked with fighting against human aging though, so maybe it does make sense.
The news is that Google is in the process of testing a contact lens which is designed to test the user's glucose levels in their tears once per second. Diabetes is a huge problem, especially in the U.S.; and, there are a wide range of complications that arise - including damage to the eyes, kidneys and heart - when glucose levels aren't monitored. The contact lens has "a tiny wireless chip and miniaturized glucose sensor", and Google is considering adding small LED lights to indicate when glucose levels cross a certain level.
Google wants to be clear that everything is still in the testing phase, although it has begun talking to the FDA and it has been looking to find partners in bringing the product to market.
