Smart Phones Save Eyes

Media Arts and Sciences Experts Design Do-It-Yourself Eye Test on Smart Phone

November 1, 2010

Media arts and sciences experts developed a do-it-yourself eyesight test that uses a smart phone and a small, plastic lens that clips onto the screen. The test can be downloaded to a smartphone from an app store. Users use the up and down keys while looking through the lens to make lines overlap on the screen. From the user's entries a prescription can be determined. The software can diagnose both near- and farsightedness as well as astigmatisms, with results emailed to a doctor directly from the phone.

MAKING PHONES SMARTER: So-called "smartphones" relate to a single device that can take care of all your handheld computing and communications needs in a single small package, integrating digital photography, cellular communication, calendars and address books, GPS navigation, email, and even play music or games. The biggest advantage is that smartphones allow users to install, configure and run their favorite applications, creating individual, tailor-made service. In contrast, most standard cell-phone software offers only limited configurations for personalizing the device.

WHAT IS 20/20 VISION? When eye doctors talk about "20/20 vision," they mean what an average person should be able to see when standing 20 feet away from a standard eye chart. This is "normal" vision. If you have 20/40 vision, when you stand 20 feet from the chart, you can only see what the average person sees standing 40 feet from it. If your vision is 20/10, you can see better than the average person: you can see at 20 feet what most people can see from 10 feet.
