## PD+ Description
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.

FITTING HEIGHT
PD+ instantly measures Fitting Heights for the frames you currently have on. Accurate fitting 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. In addition, Fitting Heights are used to position segments for fitting multifocal lenses. Please note: Fitting 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
- Rx Transposition
- Vertex Adjustment
- Crossed Cylinders (over-refraction)
- Keratometry Conversion
- Visual Acuity Scale
- Estimated visual acuity
- Minimum Blank Size (MBS)
- Simple Magnifier and Spectacle Magnifications

## PD+ Reviews in United States

### *---- "Won’t open"
Keeps crashing
-- bennett1009, 2025-08-11

### ***** "Friendly use"
friendly use and accurate.
-- frienx4ever, 2025-05-03

### ***** "Progressive lenses"
Can this app measure the PD for progressive lenses for right and left eyes?
-- this is not here, 2025-04-22

### ***** "Five stars"
Five of five
-- TadeoDK, 2024-06-08

### ***** "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
-- TheBooma, 2023-12-08

### *---- "Incorrect results"
Bad results. There’s no way my PD is 54 … don’t trust this app.
-- totsubo2000, 2023-08-05

### ***-- "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.
-- captnslo, 2023-06-22

### ***** "Artist/ painter"
Like it very much . Very convenient and will follow up and discover more detail functions
-- Little steel, 2022-09-24

### ***** "Only reliable seg height measurement app in the store"
Very accurate PD and seg height measurements
-- nhazard68, 2022-08-30
