Description of ⚖️ Hanchen Digital PD Meter with Memory Function - Pupil Distance Meter PD Ruler Pupilometer | CE Certified

【Operation】It is recommended to have a second person help you while testing. Put the PD Meter over your nose, as close to your eyes as possible. Then find the center of your pupils, the white line should be aligned with the center. The number displayed on the LCD screen is your pupil distance(Unit:mm). Please keep your eyes looking straight ahead or at the nose of your tester during the measurement. 【Precise】It is more precise than Vernier PD Ruler. The two white lines is very clear against the dark pupil and the pupil distance is displayed in the LCD screen. What's more, it can measure monocular distance separately. When two pupils centre are aligned with the white lines, press the left (right) black button, it shows the distance between left (right) eye pupil and bridge of nose. 【Warm Tips】The digital PD ruler is used to measure the distance between two pupils. This is a simple PD ruler, it can help you when you want to purchase eyeglasses online or in eyeglasses store. If you require very high accuracy, this one is not recommended. 【Powe off and Memory Function】The digital PD ruler will turn off automatically when it is set level and turn on automatically when using it to save energy. With the memory function, you do not need to worry losing data. 【Without Battery】Due to long diatance transportation, the battery is taken out. (23A,12V battery).

Good product, best electronic product

Good product. Worked exactly as advertised. Easy to use, but a second person will likely be needed. The measurement only takes a few minutes. Seems very accurate. The battery is not included, so you need to purchase it separately.

Pros
  • Easy to read control panel
Cons
  • Nothing

I was having trouble measuring my PD

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!

Pros
  • Great for a small house
Cons
  • ---

Assistance in Buying Prescription Glasses

I tried to get my local eye doctor to give me a PD but they gave me so many excuses as to why they couldn't. I wanted my PD measurements so I could get my glasses online from a site I've seen that offers prescription glasses at a much lower price. I really like this product, but for the best reason there is a second person to help get the most accurate measurements. I also found that the front windows, where the line that should be centered on the pupil, are not entirely clear, contributing to…

Pros
  • Inspires Confidence
Cons
  • Has Imperfections
