Hanchen PD Meter Digital Pupil Distance Meter PD Ruler Pupilometer with Memory Function CE Certificate

My doctor refused to give me my PD because I didn’t want to buy glasses thru them so I ordered this little to say this will give you accurate measurements! I tried it with my daughter which her PD is 55 tried it with the dice in fact was 55.

Measurements were completely accurate. I tested against a caliber just to make sure. My one complaint is the nose bridge section is too small for bigger people. My one suggestion would be to add in a headrest section so that it's perfectly snug against the face while measuring. Overall great buy.

I like this device, it came in handy. I just wish it had anti-reflective coating on the lens portion.

Not worth even close to $60. You can get the same thing that is a manual version of this for $3. Instructions don't tell you have far away you need be away from the person who is being measured.

I'm very myopic, so I had a hard time measuring my PD with a rule because with my glasses off, I could not see the rule unless I was very near the mirror, and that messes up the PD measurement because you should be focusing on something far off. These solved that problem, and I ordered several pairs of glasses from Zenni, and everything has worked out nicely. Recommend. NOTE: these need a strange battery (23A) that they do not come with, so order that, too!

The product has all the indicated specifications and works very well.

Meh just ok. Not stable enough to get totally accurate measurements.

Try to get my local eye doctor to give me my PD but they gave me so many excuses on why they couldn’t. I wanted my PD measurements so I could get my eyeglasses online from a website I saw offer prescription eyeglasses at a way lower price. I really like this product but for best reason have a second person available to help get the most accurate measurements. Also I found the front windows where the line is that needs to be centered to one’s pupil not totally clear which contribute to needing the help of a second person. Overall with a little help I did get my PD measurements and got my prescription eyeglasses for way cheaper then in store.

This instrument is perfect since your optometrist is loath to give you your Pupillary distance measurements. Without it you can’t order glasses on line. It is accurate enough to measure the same as my optometrist. I will use it for my family and friends so we can all save money by ordering glasses on line. Highly recommended. Thanks

Using this pupillary distance tool is far easier than using the basic method with just a ruler and a mirror. Seems to be well constructed of sturdy material. Have compared readings with digital pro callipers and is pretty accurate. Have not used it yet for purchase of eyeglasses and will report later after ordering eyeglasses. At least it will save those who use it the optometrist's fee of $45.00 to give out the measurement each time. If we use it twice then it's paid for itself.

Works ok. Better then a ruler. But does not come with battery and its not as good as the bigger units. Its does the job tho.
