Review on 👓 Huanyu Digital Pupilometer Optical PD Meter with LCD Display, CE Approved - 45-82mm Pupil Meter LY-9S by Marvin Perry

We were a bit apprehensive about purchasing an all digital Pd meter but took the risk as Revain offers a generous return policy. Received our device in two days and quickly checked its calibration which was perfect. It's like having an instrument with no moving parts to jam on. For example to have many distances to test. I wish the distance icons at the bottom of the screen were a little bigger to be able to see them better, but other than that it works well for our clinic.
