Pupil Distance PD Glasses & VR
How does the PD measurement tool work in Pupil Distance PD Glasses & VR?
You snap a photo of your face with a credit card for scale, and the app calculates your pupillary distance. It gave me 62.5mm on the first try, which matched my optometrist's measurement, so it's reliable for setting up VR headsets.
What is the VR calibration slider and how does it help?
The VR calibration slider lets you adjust the IPD (interpupillary distance) setting live while looking at a crosshair in your headset. This feature fixed my eye strain and blurry text during VR sessions, making it the standout reason to buy the app.
Why does the app crash when I switch between apps, and how can I fix it?
The app crashes if left in the background while switching apps, which happened to me three times in a month. To avoid this, close all other apps before opening Pupil Distance PD Glasses & VR.
What should I do if the app won't read my photo after an iOS update?
Reset the camera permissions in your iPhone settings—go to Settings > Privacy > Camera and toggle the app off and on. This workaround was provided by support after a three-day wait, and it resolved the issue immediately.
How does Pupil Distance PD Glasses & VR compare to free PD measurement apps?
Free PD apps are basic but work for a simple measurement, while this paid app ($4.99 upfront) adds a VR calibration slider and consistent accuracy. If you only need a one-time PD number, a free app suffices, but the VR slider is worth it if you frequently adjust headsets.
