PD Meter Pupillary Distance Pupillometer Tester Digital Centrometer Optical TJY-66

PD Meter Pupillary Distance Pupillometer Tester Digital Centrometer Optical TJY-66

Description:
- It is an ideal digital precision optical meter for measuring distance between human pupils in the process of optometry.
- It is designed in a scientific and reasonable way, integrating technologies on optics and microelectronics. It has the most exactitude configuration, measuring more correctly.
- It also has the focusing button for distance converting.
The pupil distance is measured by making the papillary light point and measuring light in direct line, in the way of monocular eye or binocular eyes.
