Google unveil a contact lens that monitors glucose levels in tears.

The lenses use a minuscule glucose sensor and a wireless transmitter to help those among the world's 382m diabetics who need insulin keep a close watch on their blood sugar and adjust their dose.
The prototype, which Google says will take at least five years to reach consumers, is one of several medical devices being designed by companies to make glucose monitoring for diabetic patients more convenient and less invasive than the traditional blood-drawing finger pricks.
"We're testing a smart contact lens that we built that measures the glucose levels in tears using a tiny wireless chip and a miniaturised glucose sensor," explained the Google X project leader for the smart contact lens, Brian Otis.
The device, which looks like a typical contact lens, contains two twinkling glitter-specks that are loaded with tens of thousands of miniaturised transistors and is ringed with a hair-thin antenna.
"We've had to work really hard to develop tiny, low-powered electronics that operate on low levels of energy and really small glucose sensors," Mr Otis said at Google's Silicon Valley headquarters.

I can see how this could work,
My eyes are very sensitive after years of treatment but I can very accurately read my bg levels from the state of my vision.

I somehow felt that it was not the retinal blood vessels at work.I suppose there could be problems with contact lenses but that on the whole the idea is an improvement on the blood tests in many ways.

There remains the question of cost of course.
