Smartphone-based eye exams

One of the innovations that improved the world in 2014 is the Smartphone-based eye exams According to Matt Petronzio, Scientists at Stanford University have developed a sensor that can monitor glaucoma using a tiny device implanted in the eye. The technology, which can be used with a smartphone camera, has the potential to prevent blindness for people around the world. Glaucoma inflicts progressive damage on the optic nerve, but it usually doesn't have other symptoms besides loss of peripheral vision (which can be difficult to notice right away). The implant, which is only a few millimeters long, measures intraocular pressure (IOP) in the eye, which is imperative at critical stages of glaucoma. The tech has seen success in animals, and, as of September, is undergoing trials in humans.

A similar smartphone app, Peek, launched a crowdfunding campaign in November to increase access to high quality eye care across the globe. Funders can purchase the kit for themselves or for health care workers through Doctors Without Borders or the International Agency for the Prevention of Blindness. It's expected to ship in October 2015. read more of the other innovations at http://mashable.com/2014/11/29/social-good-innovations-2014/ IMAGE: TONY KARUMBA/AFP/GETTY IMAGES
