SAN FRANCISCO (KGO) -- Google is stepping up its game in the health world.
It's been granted a patent for "smart" contact lenses.
The lenses are "smart" because it's able to test people's blood glucose levels through an embedded chip.
A tiny hole in that chip allows tears to flow through and then the chip acts as a sugar test strip.
Google says this could eventually replace the finger prick millions of diabetics have to do now.
