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. Both far and near PD's -- binocular & monocular -- are available at no cost.
SEG HEIGHT
PD+ instantly measures Segment Height -- or Seg Height, for short -- for the frames you are currently wearing. Accurate seg height and PD measurements are both necessary to ensure viewing through the optimal zone of the lens when relensing a pair of frames. 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).
CALCULATORS

- Estimate acuity from refractive error
- Minimum Blank Size (MBS)
- Simple Magnifier and Spectacle Magnifications
* Unlike other PD apps, core functions including PD and optical math tools work on ALL devices running iOS/iPadOS 15 and later *
