Introducing new technology isn’t always easy. A project to create a glucose-sensing smart contact lens to help people with diabetes is being put on hold.

Verily is part of Google and began working with pharmaceutical firm Novartis and its Alcon eye division in 2014 to develop the smart contact lens. This included a lens that measured glucose levels in tears to help those with diabetes manage the disease.

However, the firm has now said the level of glucose it was detecting in tears did not compare closely enough to the levels found in blood during testing.

Why work has stopped on the smart contact lens

“Our clinical work on the glucose-sensing lens demonstrated that there was insufficient consistency in our measurements to support the requirements of a medical device,” the company said in a blog post.

“We are at a point where we have decided, together with Alcon, to put the glucose-sensing lens work on hold.  (We’ll continue) to focus on the smart accommodating contact lens and smart intraocular lens projects.”

These other other smart contact lens are being developed to help improve the sight of those who have just undergone cataract surgery.

Verily added that it would continue to research glucose-sensing technology that was “inexpensive and unobtrusive”.
