According to the World Health Organization, glaucoma is the second leading cause of blindness worldwide. Glaucoma is basically a build-up of pressure in the eye. It can not be permanently cured. Now researchers at UC Davis have designed a special kind of contact lens that can measure pressure build up in the eye and they’ll even give you a warning if anything is wrong.

These smart contact lenses use an organic polymer called PDMS that acts like a pressure sensor. UC Davis says that they will start clinical trials of these lenses in humans very soon. But this isn’t the end of the breakthrough, they’re also working up to one that will dispense medication automatically.
