Smart contact lens from Google: Usable for medical purpose

Google working on a smart contact lens, which will helpful in medical purpose. The device will be used in medical science and could measure the level of glucose in your tears. Diabetic's patients can also measure and monitor their condition without needles and blood.

A small wireless chip and glucose sensor are impacted between two layers of “biocompatible” contact lens material. A tiny light has also been fixed in the device. The device is in progress and Google is also taking with FDA to confirm the technology ticks.

Google writes the words in their official blog.

"We’re now testing a smart contact lens that’s built to 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. We’re testing prototypes that can generate a reading once per second. We’re also investigating the potential for this to serve as an early warning for the wearer, so we’re exploring integrating tiny LED lights that could light up to indicate that glucose levels have crossed above or below certain thresholds. It’s still early days for this technology, but we've completed multiple clinical research studies which are helping to refine our prototype. We hope this could someday lead to a new way for people with diabetes to manage their disease”
