A research team has developed wirelessly driven smart contact lens technology that can detect diabetes and further treat diabetic retinopathy just by wearing them.

The wireless smart contact lens can diagnose and treat diabetes by controlling drug delivery with electrical signals. The lenses are made of biocompatible polymers and integrate biosensors, drug delivery, and data communication systems.

The research team verified that the glucose level in tears of diabetic rabbits analyzed by smart contact lenses matched their blood glucose level using a conventional glucose sensor that utilizes drawn blood. The team additionally confirmed that the drugs encased in smart contact lenses could treat diabetic retinopathy.

They are expanding the scope of electroceuticals that use electrical stimulations to treat brain disorders such as Alzheimer’s and Parkinson’s diseases, and mental illnesses including depression.
