Google reveals contact lens for people with diabetes
Google has unveiled a protype contact lens that monitors glucose levels in tears.
The technology giant hopes that the lens could one day replace traditional finger jab tests that some people with diabetes have to endure up to 10 times a day to test their blood sugar.
The lenses, which use a minuscule glucose sensor and a wireless transmitter, will take at least five years to reach consumers, Google says.
