Pupil Distance PD Meter Pro
Does Pupil Distance PD Meter Pro measure each eye separately?
Yes, the app allows you to measure each eye individually, which is helpful if one eye's PD is slightly different from the other. This gives you more detailed results than a single combined measurement.
Does the app have a history log to track past measurements?
Yes, it automatically saves every measurement attempt in a history log, so you can see all your results side by side. This makes it easy to spot inconsistencies and even average them yourself for a more reliable number.
Why are my PD measurements inconsistent, and how can I fix it?
Inconsistent readings often come from poor lighting or slight head movement. For best results, use the app in bright, diffused natural light, like near a window on a sunny morning, and hold your phone steady in the guided face outline.
The app keeps telling me to hold still, but the circles jitter. What should I do?
This usually happens in low or harsh lighting, like under a direct overhead light. Try moving to a well-lit area with soft, even lighting, and make sure your face is fully inside the on-screen outline before tapping the measure button.
How does Pupil Distance PD Meter Pro compare to other PD measurement apps like GlassesOn?
Unlike some apps that send your facial data to external servers, PD Meter Pro processes everything on your device, which is better for privacy. However, its accuracy can be inconsistent in poor lighting, whereas some competitors may handle low-light conditions more reliably.
