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
Im optometrist and i found this app is really great, both the flow how it runs and functions, just some minor things need to be changed to be come core app for those practicians like me:
Fantastic app. Great for remote use - when patients can't get to a city for eye checks. Even better that it can all be controlled by your phone and it will calculate the appropriate measurements for testing.
Easy to use
Very straightforward app. Does what it says with some nifty features!
