This Contact Lens Uses Graphene to Check Your Glucose Levels

Popping in a contact lens could soon protect you from a diabetic attack. The lens, which has a tiny plastic nanostructure embedded in it, provides realtime alerts before blood sugar levels become dangerous – and it could be mass-produced in the next five years.

Researchers at the Ulsan National Institute of Science and Technology (UNIST) and Sungkyunkwan University in South Korea made the breakthrough by squeezing a minuscule LED display embedded inside a contact lens, which alerts the wearer when their blood sugar levels are too low.

“Diabetic patients need to monitor their glucose levels a few times per day,” says Jang-Ung Park, an associate professor at the UNIST who worked on the project. “Currently they do this through their blood, so non-invasive methods are preferred.”
