The MOST accurate visual acuity test on the iPad (or iPad mini).
A built-in auto-calibration function on the iPhone/iPod will adjust the size of the Snellen Chart (and brightness) to produce accurate and reproducible results.
The iPad chart is fully functional, but the best way to use the app is with the iPhone/iPod remote (this requires an in-app purchase for full functionality).
An auto-dim function is set to time the screen out at 2 minute to prevent the iPad battery from being depleted (this is now user adjustable).
Tested with all iPad versions (maximal chart distance 7.4m/24ft), and with the iPad mini (maximal chart distance 6m/20ft). Tested with all current iPods with a built-in camera and iPhones except the iPhone 3.
The app has been tested by Ophthalmologists, feedback is encouraged.
Updated to ios8. The option to toggle 6/5 Snellen line added.
Auto-calibration of some of the newer devices may not be accurate - feedback to fine tune this is appreciated.
Ratings and Reviews
Remote no longer working
Was working wonderful to screen vision during mass screening students by school nurses. But the remote will no longer connect after the upgrade to iOS 10.
The missing instructions prevent this from a 5 star rating, but your intuition should suffice. Also, wish measurements were not metric. For a quick eye test this is more than adequate on an iPad.
Easy to use
Very easy to use and easy to set up. Very useful for school screenings and other out-of-office eye exams.
