|Accuracy Test Results|
Pupil Distance Meter is a tool for PD measurements using a camera on your mobile device.
iOS version of the app uses improved approach, which allows you to achieve more accurate and consistent measurement results.
On the left you can see results of accuracy tests taken with Pupil Distance Meter on iPhone.
In accordance with the measurement procedure, two successive pictures were taken from different distances to get an average result. Then pupils and the credit card were carefully marked with the special rulers on the screen. As soon as the layout of the features were confirmed with BOTH switch controls at the bottom right corner, correct PD distance were calculated and shown at the top of the screen.
As you can see on the picture, the result from the app is very close to the true data measured with a usual ruler.
You can achieve the same good results, if you thoroughly follow the instructions and tips from one of our previous posts about Pupil Distance Meter on iOS.
