WHY NEED A PD MEASURING RULER?
Pupillary Distance or PD is the distance between the center of our pupils in millimeters (mm). It is an important data when purchasing prescription glasses online, because it determines comfort and how well our glasses can fit. We can get the PD measurement on our prescription by our doctors, but if we cannot find it, or if we are going to by glasses online, we will need this PD ruler to measure the Pupillary Distance

I got this so I could purchase online glasses, couldn’t figure out how to use even after watching video tutorials. I ended up browsing glasses in person at an eyeglass shop and they gave me my pupillary distance. I think most office charge for this so just “pretend” lol to buy glasses if you need this measurement that bad idk worked for me. This item is cheap in price and quality. Buy only if you need it as a last resort.

I like this ruler, it lets you measure your face for a pair of glasses, as the eye doctor typically doesn’t include your pupillary distance on the prescription.I was able to get a perfect set of glasses online using this tool and my current prescription.The numbers can be a bit hard to read, but you can always use a friend to help you.

Good ruler. Has a dual as well as a monocular PD scale, which helps in confirming your measures.

Works as intended. I think the price is way too much to spend on a little piece of plastic, but with COVID restricting normal life, online is about the only way to shop.
