Precision Optical Instrument: The Pupillometer is designed to measure the interpupillary distance (IPD) during eyeglass refraction. It features direct point sampling and high positioning accuracy.
Measurement Accuracy: Delivers a measurement error of less than 0.5mm, ensuring highly reliable results.
Easy Operation: The PD Meter can be turned on/off with a single press of the power button. It automatically powers off after use to conserve battery life while retaining settings. The system eliminates parallax errors.
Ergonomic Design: Equipped with a stainless steel forehead rest and soft rubber nose pads for comfort and precision during measurements.
PD Toggle Key: Features a clear digital display for instant readability. Directly measures distance PD, and pressing the PD key calculates near PD automatically.
Description
Optical Digital Pupillary Distance (PD) Meter
Types of PD Measurement:
Binocular PD: Total distance between both pupils (e.g., 63 mm).
Monocular PD: Distance from the bridge of the nose to each pupil (e.g., 31.5 mm per eye).
How to Use a PD Meter:
Look into the device while focusing on a target light.
Sensors automatically calculate PD.
