Eye Phone: MIT Researchers Develop Ultra-Cheap, Smartphone-Based Eye Exam Tool | Fast Company


Measuring someone for an eyeglass prescription usually requires bulky diagnostic machines or high-tech laser scanners that can cost thousands of dollars. Which means that in the developing world, vision correction is often an unattainable luxury for literally hundreds of millions of people. But a team of researchers at the MIT Media Lab has unveiled a system for prescribing eyeglasses that requires nothing more than a smartphone and a $1 plastic lens attachment.

Cool at $1! =) This is innovation!
