Review on π Huanyu Digital Pupilometer: CE Approved PD Meter & Pupil Distance Measuring Tool (LY-9C) by Ken Barnett
No build quality
Everything seems to be fine. I can doubt the calibration. Slightly different readings than my other devices. The shutter switch that switches from monocular to binocular is loosened. It has a little game. This makes me feel like the build quality could be better.
- MONOCULAR MEASUREMENT AVAILABLE: It can be used in a monocular to measure left and right eyes separately, and the readings will be displayed separately.
- Only available in black
