Google is reportedly developing a smart contact lens that will measure a wearer's glucose levels by testing their tears.In a patent application, Google showed off potential designs for how it could package a smart contact lens.
Google has previously said it is speaking to the US Food and Drug Administration (FDA) about potentially testing its lens, and that general availability of the contact lens is most likely at least five years away.
The lens the company announced it is working on would be able to gauge a wearer's glucose levels by just analysing tears.
This could potentially remove the need for diabetics to prick their fingers and draw blood to check their blood-sugar levels.
