Smart contact lenses could help diagnose and treat diabetes

A team of researchers at POSTECH, Pohang University of Science and Technology, developed a smart contact lens technology for "both continuous glucose monitoring and treatment of diabetic retinopathy". The contact lenses were tested on diabetic rabbits and were able to measure glucose levels in tears that matched their blood glucose levels. The team has also confirmed that the technology could trigger the release of drugs encased in the contact lenses to treat diabetic retinopathy.
