Google's Smart Contacts Could Save Diabetics a Lot of Pricks

Google is taking the wearable tech trend to a new level. The company has announced it is working on smart contact lenses that measure the level of glucose in one's body. Diabetes affects around one in 19 people in the world, many of whom struggle to control the levels of blood sugar in their bodies, Google said. Blood sugar imbalances can lead to issues with eyes, kidneys and hearts. Most diabetics need to prick their finger and test blood during the day. Many check their glucose levels less often than they should, due to the discomfort and disruption associated with those tests.
