Picture of the Day: Smart contact lens detects blood sugar levels
Even contact lenses are getting smart.
Aiming to help people who are struggling with managing diabetes, a contact lens is being developed to measure glucose levels in tears. It uses a very small wireless chip and a miniaturized sensor that can detect glucose. The chip and sensor are embedded between two layers of soft contact lens material.
Brian Otis and Babak Parviz, both from Google, are the people behind the project.
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.
They are currently in discussions with the FDA, but admit there’s plenty more work to do to make the technology mainstream. They are planning to look for partners to help bring it to market.
