Features

  • SIMPLE & ACCURATE: PD Meter is a precision optical instrument used to measure distance between pupils in the process of optometry for spectacles. Compared with those printable rulers, our digital PD meter adopts high precision sensor and advanced intelligent electronic system to display the measurement results digitally, which is intuitive, accurate and easy to operate.
  • MEASURING ACCURACY: 0.1/0.2/0.5mm is adjustable: According to the accuracy requirements of the actual glasses, set the measurement step increment, that is, accuracy, instead of fixed 0.5mm, the measurement results are more reliable.
  • 30CM- ADJUSTABLE VISION DISTANCE: The 9A pupil distance meter is equipped with a Stadia Knob unique to the upgraded model. Can set 30cm, 40cm, 50cm, 1m, 2m, and other different vision distance gears.
  • MULTIFUNCIONAL: Our pupilometer also has the following functions: Stop using for 3 minutes automatically shut down; Shutdown automatic memory last value (No machine operation during this period); 0.5-3.0 degree LED energy-saving lamp brightness adjustable; + 2.00d visual acuity compensation.
  • PROFESSIONAL AND RELIABLE: Huanyu is a professional enterprise specializing in the design and production of various glasses optometry equipment. Compared with other low-cost brands, our PD Meters have a more professional production process, are made of higher quality materials, and have a more comprehensive after-sales service.

    • Saved me a lot of money in the end...
Color: Ly-9at
I have had glasses since i was 10 years old (42 today), so i understand the need to accurately measure the PD. I have been using brick/mortar stores for decades and never had a problem until the pandemic hit. For some reason, the number of frame options that would be fit my very high script dropped drastically. in fact, one sat afternoon, i visited 9 individual optical stores (chains and individual) and could only find large/plastic style frames, when previously, i could easily find multiple metal rectangular frames. i gave up and started looking online. I used wirecutter to find a good store and proceeded to figure out how to measure my PD. The website says to use a ruler, which seems wildly inaccurate, so i tried several different iphone apps, all which gave me slightly different PDs. I finally ordered this device, realizing that someone must sell what they use at store. Lucky me as i was able to take the measurement and it stayed consistent over the course of a week (yes, i took 7 measurements). i ordered the glasses online and so far, they fit great and my eyes are doing great (i.e. minimal adjustment time and no eye strain). while the price of the glasses wasn't an issue (i have gotten to use to the high price over the years), ordering online for the same frame as i could get in stores saved me hundreds (literally), so spending the money on this should be help me save more in the long run. ... show more

    • Disappointed. Maybe a fluke.
Color: Ly-9at
The device is well made and sturdy. However to get an accurate measurement there needs to be a focal point for measurement. The instructions state that to remind the “testee to stare at the green target” but no green target is visible. Batteries are installed measurement tools appear to be functional but this device is worthless if you’re unable to measure from the focal point. Returned and will try another device. ... show more

    • Doesn't Give Consistent Results for Monocular Measurements
Color: Ly-9at
I had my PD measured by two different opticians using Essilor X81705 pupilometers and they both had the exact same measurements for both monocular and binocular tests (31.5 mm left, 33.5 mm right, 65 mm total). While binocular (combined monocular) readings with this pupilometer were always within 1 mm of the Essilors, we could not get duplicate monocular readings out of 10 attempts. The averages of the 10 pairs of monocular readings were about 1 mm left of those of the Essilors. For single vision lenses, this may be acceptable to most people but not me. My optometrist showed me that a 1mm shift reduced my corrected 20/15 vision to somewhere between 20/20 and 20/25. Once you've experienced 20/15 vision, 20/25 won't do. It appears that the reason for this discrepancy is because the nose piece for this pupilometer is much smaller and much narrower than the Essilor's. It is almost impossible for me to get it to rest in exactly the same position and orientation on my nose from one measurement to the next. I suppose it may work for children and for people with narrow noses, but it didn't work for me. ... show more

    • A must-have tool for buying eyeglasses online
Color: Ly-9at
I buy glasses online and suspected that the pupillary distance I was providing was the reason for the glasses to be off. Given that the optometrist who updated my prescription refused to measure my PD distance unless I bought glasses at his store, I tried to measure it myself, using several methods, including rulers, credit cards, cellphone apps, and eyeglasses measuring frames, but none seemed trustworthy. I got this Pupilometer and immediately realized how bad the other methods are. With this tool, you obtain reproducible measurements. You also get the PD distance for each eye. In addition, you get the PD for distance vision or reading vision or a distance in between (selectable with a dial). With the PD measurements taken with this tool, which differed from the measurements taken with other methods, my new pair of distance, intermediate, and reading glasses were spot on. ... show more

    • Excellent Product, Value and Customer Service
Color: Ly-9ac
This company went above and beyond to make sure we got the correct item for our needs. Extremely fast shipping and great communication. The pupillometer works well and is good value for the price. It runs on batteries that need to be charged to the wall so make sure you are ok with this detail.

    • Wish it had worked.
Color: Ly-9ac
Regretfully, I did not open this to try to use it until I'd had it for a year and a half. My mistake. One of the battery terminals inside is missing, so the batteries slosh loosely inside and cannot power the device. So, I thought to plug it in, but it's got an EU plug. The pictures show this -now- but, when I purchased it, this was not apparent! I've never actually seen one in real life before now. Either way, this was less than useful. Wish I'd saved the money. ... show more

Had to buy this because ours broke at work and needed in a pinch. It has surprisingly held up great and a fraction of the cost of other “name brand” ones
