Review on ⚖️ Hanchen Digital PD Meter with Memory Function - Pupil Distance Meter PD Ruler Pupilometer | CE Certified by Athenasby Whitney

I am very nearsighted so it was difficult for me to measure my PD with the rule as without glasses I couldn't see the rule, it unless I was very close to a mirror and it interferes with the PD measurement because you have to focus on something far away. That solved the problem and I ordered several glasses from Zenni and everything went well. I recommend. NOTE: You will need a weird battery (23A) that is not included, so order that too!
