NETRA, created in MIT's Media Lab, is a device that attaches itself onto cell phones in order to diagnose eye prescriptions in developing countries or rural areas that don't have access to more sophisticated optometry equipment.
NETRA, which stands for Near-Eye Tool for Refractive Assessment, could really revolutionize eye care around the world. Because the device uses cellphones, an already ubiquitous tool in developing countries, NETRA's accessibility is far-reaching.
