V0 LCD Digital Pupilometer Optical PD Meter Interpupillary Distance Tester

Description

It is an ideal digital precision optical meter for measuring distance between human pupils in the process of optometry.
With the scientifical design and technologies in optics and microelectronics, this device has the most
exactitude configuration,
and is able to measure more correctly. It also has the adjustable focusing knob to adjust the distance.
Moreover, the lens is coated. The pupil distance is measured by making the pupillary light point and
measuring light in
direct line, in monocular or binocular way.
