| Portable Cellphone Add-On For Vision Test |
 Cell phones come with all kinds of applications these days, but researchers at MIT have developed one with the power to change more than just a Facebook status. Using a small plastic lens that clips to a cell phone screen, the software can determine a person’s vision prescription on the spot, making quick, inexpensive diagnoses of refractive vision errors a reality, especially in remote areas of the world.
The test itself is simple. The patient looks through a lens in the clip-on device at the cell phone’s screen, using the arrow keys on the phone’s keypad to move sets of parallel green and red lines around until they overlap. Do this eight times for each eye and the software in the phone can determine your prescription. The entire process takes no more than two minutes.
