Pupil Distance Meter allows you to measure pupillary distance (PD) automatically using your Android camera.
Pupillary Distance is needed when you want to order eyeglasses. Now you can measure it yourself using this app. You have options to measure the PD automatically or adjust it manually.
Millimeters or inches are used to show the results.
The black magnetic stripe on cards (e.g credit card) is used as a reference for measurements.
