Researchers at MIT Media Labs have developed an application called NETRA — Near-Eye Tool for Refractive Assessment — for eye exams. The App produces results comparable to standard tests performed by optometrists.
The patient looks into a lens and uses arrow keys on the phone to make sets of green and red parallel lines overlap. The phone then changes the angle of the lines, asking the user to the same test again. After performing the task eight times with each eye, a process that takes about two minutes, the application processes the results and spits out prescription data.
