It may be best known for its interactive Glass specs, but Google today revealed a radical smart contact lens for diabetics.
It analyses their tears, warning them if their glucose levels are low.
The search giant said it hoped to develop other apps for the smart contact lens, which could one day even show wearer’s other types of information and include tiny screens.
Google is testing a prototype for a smart contact lens that we built to measure glucose in tears continuously using a wireless chip and miniaturized glucose sensor.
HOW IT WORKS
The smart contact lens can measure glucose levels in tears using a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material.
Prototypes generate a reading once per second.
Google is also investigating the potential for this to serve as an early warning for the wearer, integrating tiny LED lights that could light up to indicate that
