## Questions & Answers

**Q: How do you measure monocular near pd at 40 cm?**
A: It is directly converted by the button, that is, the interpupillary distance is measured as before, and then press the PD button, it will display the data of 30CM, and press it again to get the data of 40CM

**Q: Does this actually measure PD at multiple distances, or are the non-infinity measurements calculated by computer?**
A: Our interpupillary distance meter can measure the interpupillary distance at many distances. If you are a handicraft maker and need to work frequently with eyes and hands kept at a distance of 30cm(11.8inch), you can set the distance to 30, and then measure the distance between the interpupillary distances to process glasses. 
It means that you can measure the interpupillary distance when the eyes look at different distances. 
If you need to measure the interpupillary distance between myopic eyes to equip myopia glasses, you can choose infinity. 
We generally default to measuring at infinity.

**Q: Where is this made?**
A: Made in China.

**Q: Will this device measure distance pd or reading pd or an intermediate? how do you interpret the results to order progressive lenses?**
A: It is the PD distance. In addition, the progressive lens has nothing to do with the interpupillary distance meter, it depends on your own needs~
Looking forward to your order.

### ⭐⭐⭐⭐⭐ Saved me a lot of money in the end...
*by A***S on January 6, 2023*

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.

### ⭐⭐⭐⭐⭐ Works well at much less than the traditional name brand devices
*by L***N on June 25, 2024*

Purchased this for my optical. Have been using for a while. Not flashy but works and provides the info that I need. Much less expensive than the usual "name brand" manufacturers.

### ⭐⭐ Disappointed. Maybe a fluke.
*by L***8 on October 15, 2023*

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.
