설명

PUPILLARY DISTANCE
PD+ instantly measures pupillary distance (PD) by capturing & processing a single, hi-res facial photo. Measurement accuracy is guaranteed to be the highest achievable by the capability of your device's camera system. Far and near PD's -- binocular & monocular -- are always available at no cost.

SEG HEIGHT
PD+ instantly measures Segment Height -- Seg Height -- for the frames you are currently wearing. Accurate seg height and PD measurements are needed to ensure that lenses being made for your frames are properly centered on your eyes to achieve optimal viewing clarity. Please note: Seg Height is currently only supported on devices equipped with the TrueDepth or LIDAR camera systems (e.g., iPhone X and later non-SE models).

Works great

There were a couple others that I tried but this one worked great. It even has voice instructions. I would highly recommend this app

Thank you for your feedback! We are very glad that you have found PD+ to be useful.

Friendly use

friendly use and accurate.

PD not quite there

Using an iPhone SE. PD’s for myself and my coworkers were constantly off by 4-6 mm. Calculations are a great tool to have for the pocket access, but since most people will probably use this to measure their PD for online glasses prescriptions, I would not recommend this. Best to get it measured by a real optician.

We really appreciate your honest review. The iPhone models with a single-lens camera (includes SE and devices that came before iPhone X) pose a challenge due to the lack of depth imaging capability. However, we are always finding ways to squeeze out more performance in all devices running at least iOS 15. We hope you would consider updating your review in a future PD+ release.
