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.

“Our clinical work on the glucose-sensing lens demonstrated that there was insufficient consistency in our measurements of the correlation between tear glucose and blood glucose concentrations 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, while continuing to focus on the smart accommodating contact lens and smart intraocular lens projects.”
The latter of the two other contact lens devices being developed is being designed 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”.
The company began life as part of Google’s X lab of futuristic research projects, before becoming an independent firm within Alphabet as part of its “graduation” from Google’s internal labs.
