Google's smart contact lens may arrive sooner than expected

Google's smart contact lens that will measure glucose levels in diabetics by analysing their tears may be on the market before 2019.

In a recent patent application, Google showed off potential designs for how it could package a smart contact lens, suggesting the project could be further along than thought.
Last year, the company announced that it was working on a lens that would be able to measure a wearer's glucose levels by analysing their tears.

The lens could potentially remove the need for diabetics to prick their fingers and draw blood to check their blood-sugar levels.

Google has previously said that general availability of the contact lens is most likely at least five years away.

However, for a project that is supposedly in the research phase, it seems an interesting step to apply for a patent on how to package the product for consumers, according to Quartz.
A representative for Google said that product releases can not be inferred from patent applications.
