## Description

PD Ruler

Review: I couldn't be more satisfied with my experience! - I recently purchased the Measure Optical Vernier PD Ruler Pupil Distance Meter, and I couldn't be more satisfied with my experience! This ophthalmic tool is incredibly accurate and easy to use. The Vernier scale ensures precise measurements of pupil distance, which is crucial for fitting glasses correctly. The build quality is solid, and the tool feels durable while still being lightweight for convenience. It’s also designed with clear markings, which makes reading the measurements straightforward even for those with minimal experience. Whether you're a professional optometrist or just someone looking to measure their PD at home, this tool provides excellent results. Highly recommend it for anyone needing a reliable and accurate way to measure pupil distance!
Review: Its a great tool to have when ordering your own glasses - It took me a minute to figure it out because it didn't come with instructions I had to google it. My sons glasses come in and he sees perfectly. The measurements are spot on once you know how to figure out how to read the PD. I would definitely purchase it again if I needed to because it is thin and can break easily but so far so good you definitely don't want your child or pet to get ahold of it.

## Questions & Answers

**Q: Can someone please explain how to use this?**
A: I'm guessing most people here are here because of Zenni Optical? :P Here's how to measure your PD: (1.) Place the 0 line over the center of your pupil in your right eye. Move the center piece to the middle of the bridge of your nose. Write down the number (in the picture, it's 2.8). (2.) Move the left piece so the line is in the center of your left pupil. Subtract that number from the middle number (in the picture, that's 5.7, so it'd be 5.7 minus 2.8, which is 2.9) (3.) multiply both numbers by 10. In the pictured example, your right PD is 2.8 * 10, or 28. Your left PD is 2.9 * 10, or 29.

**Q: Is this the same as USA version.**
A: No it's not. I don't know how to use it myself. I am going to order one that I can understand. Don't get this one.

**Q: Returnable?**
A: Yes, I did return mine because I could not get the proper measurements even with another persons help.

**Q: Can you use this alone or with help?**
A: It's a lot easier with help

### ⭐⭐⭐⭐⭐ Its a great tool to have when ordering your own glasses

I would definitely purchase it again if I needed to because it is thin and can break easily but so far so good you definitely don't want your child or pet to get ahold of it.

### ⭐⭐⭐⭐ It's fine
*by C***. on December 28, 2024*

Is it cheap plastic and cheaply made? Sure. Is it inaccurate? No not at all. I saw other reviews saying they compared to other rulers and the ruler they used was a printable ruler. If you know anything about printing it's that most full page documents/images may shrink or enlarge itself to fit the page it's printing on giving an unreliable comparison. I lined this up with a metal yard stick and 100mm on this device lined up exactly with 10cm on the yardstick.
