Here’s a wild new app is being developed and tested out of the Massachusetts Institute of Technology’s Media Lab Camera Culture group, reports AOL’s Small Business.
According to the article, "Here’s how it works: The user downloads the app, places a $2 lens over the screen, sticks an eye up to it and follows a series of exercises presented on the smartphone. Align the patterns and the app will be able to tell just how bad or good your eyesight is. The process takes just a few short minutes."
