This glowing contact lens could help prevent blindness in millions of people with diabetes.

Hundreds of millions of people suffer from diabetes worldwide, putting them at risk for a creeping blindness, or diabetic retinopathy. Existing treatments, though effective, are painful and invasive, involving lasers and injections into the eyeball. Graduate student, Colin Cook working in Professor Yu-Chong Tai’s laboratory has invented a contact lens that when worn during sleep interrupts the process that destroys cells of the retina. He hopes his contact lenses will offer a solution that patients will be more willing to try because the effort involved is minimal, as are the side effects. [Caltech story]
