Google’s ‘Smart’ Lens Could Help Diabetic Patients Monitor Glucose
Google (NASDAQ:GOOG) announced a new product Thursday on its blog that brings to mind a science fiction novel: a “smart” contact lens with the ability to help diabetics monitor and control their blood sugar.
In order to check their glucose levels currently, diabetics must prick their finger and test drops of blood throughout the day. But the practice, which many find disrupts their day in addition to being painful, means that a number of people don’t check their blood sugar levels nearly as much as they should.
Google‘s contact lens, in contrast to conventional ways of monitoring glucose, uses tears rather than blood samples to measure blood sugar. Scientists have long thought that tears and other body fluids could provide alternative ways to measure glucose levels. The problem, of course, is that unless a patient can cry on demand, tears are difficult to collect and study. According the company’s blog, Google speculated that super-miniaturized electronics could be “a way to crack the mystery of tear glucose and measure it with greater accuracy.”
