Google Labs developed a diabetes glucose meter inside a contact lens.
An early, outsourced clinical research study with real patients was encouraging, but there are many potential pitfalls yet to come, said University of North Carolina diabetes researcher Dr. John Buse, who was briefed by Google on the lens last week.
“This has the potential to be a real game changer,” he said, “but the devil is in the details.”
Among those is figuring out how to correlate glucose levels in tears as compared with blood. And what happens on windy days, while chopping onions or during very sad movies? As with any medical device, it would need to be tested and proved accurate, safe, and at least as good as other types of glucose sensors available now to win FDA approval.Associated Press in the Washington Post
I’m skeptical. I’ve seen so many attempts at making pain-free-zero-blood glucose meters. All have failed to produce accurate and consistent results. It would seem there is no substitute to measuring blood serum.
