Contact Lenses of the Future Will Treat Your Eye Diseases

Tingrui Pan and Hailin Cong, researchers at UC Davis, have designed a contact lens that keeps tabs on glaucoma all by itself. And they’re working up to one that dispenses medication automatically, too. Their smart lenses are fitted with an organic polymer called polydimethylsiloxane (PDMS), which is commonly used in biological applications. Since glaucoma develops as a result of raised pressure inside the eye, the goal of the lenses is to detect that intraocular pressure and mark warning signs
