Pupil Distance Meter | PD Camera Measure

garbage

Is ok.

Very useful, we just used our common sense!

So complicated it isn't even worth downloading!

Dr said 64, This app said 63.5, so it's right on the mark if you follow the instructions carefully. If the credit card is on the same plane (even distance from camera) as with the eyes and not tilted, and camera straight on at arms length it works perfectly. Remember, if you tilt the card it will look and measure smaller and thus your PD will measure will be too large.

First I will say that I do infact have access to an optometrist grade pupilometer and so I have something to compare this to, and it was extremely accurate when measuring the rest of my family, however got mine quite a bit off which I will now explain what I believe to have hade the difference. The difference is truly in getting the correct alignment of the card and the position of the eyes. When attempting to measure my own PD I was using the front camera and looking at the phone trying to see and press the shutter button, and trying to align the card by feel, whereas when measuring my family members, I was able to see the card and eyes and get proper alignment and also they were looking straight ahead instead of at the phone screen. Overall I would say the concept and accuracy of the app are spot on with proper alignment, but looking straight ahead your eyes will be positioned slightly different for focus than if you are focused on the phone screen and the alignment and size of the reference card matters, for best results have somone give you a hand with card alignment and taking the picture and you will get an accurate reading. I definitely agree that an app like this was worth it as most eye professionals will typically refuse to give you a reading unless you are ordering glasses directly from them, and even then they are hesitant to give you the numbers, hence the reason I spent the money getting my hands on a pupilometer on amazon in the first place.

Would not recognize any pupils, on anyone I tried the ap on. Used different lighting in different rooms, even with florescent lighting. When i used the manual settings it keapt givind differnt readings. What a wast of money.

It was not done well. You match up the card with the green area then it doesn't match with your eyes. Your eyes centered don't match with the card. I was better saving my two dollars and sticking with the measurement I got from PD ruler. I found for free on internet. I just wanted to make sure I did properly because I ordered glasses.

No sirve. Use una regla de milimetros y una camara y funciono eso mejor que el programa

This app works pretty well but you have to spend some time and follow the instructions. Once I made sure the reference card was in the same plane as my eyes and the camera was arm's length away (so that it doesn't distort as much) I started getting results within 1.5mm of each other. I took several shots, averaged them, and came up with a useful number. Took about 15 minutes to get it right. Galaxy S7 with the back camera so I could use flash.

I tried about 6-7 times and knew the results weren't correct because the card wasn't parallel to the camera or my head wasn't. I finally decided to stick the card to my forehead, so at least if my head was good everything else would be. The next hurdle was that I was trying to align the green outline of the digital card to my card and that always yielded slightly off results. Just focus on putting the center marks on the outside radius and it will be golden. PD was verified by OD later :)

Worthless... while I was using it for my own glasses' purchase, I thought I might also be able to use it in my math classes. Unfortunately, the variation in results make it useless for both purposes. I got readings of 48.7, 54.7 and 60.6; I used zoomed in pictures and was exacting in placing the green bar's endpoints. Very disappointing.

Better to jus go in to any eyeglass store to get the right number. This was off by 15 to 20 every time. To late for the first pair of glasses I order trusting this worthless app.

Used it when brought it this afternoon then when I went back into it, it wouldn't open. Waste of time and money

I have my own PD from the optometrist (near, inter, distance) but wanted to check my wife's PD. I have 64, and this app got me 64.5mm - but the photo and alignment of the card do have to be good.

It would be nice if you could toggle a super slow movement of the alignment circles. Other than that it's fairly accurate if you set it right.

I measured myself with a ruler and then tried this app. I had to try a few times but the measurements from the ruler and app were only different by .9mm . I would say that this is fairly accurate. I'm glad i bought it.

So complicated it isn't even worth downloading!

It's like a refund please as I can't use this. I tried uninstalling and reinstalling.

Great little app. Does exactly what it's supposed to.

garbage

The directions just state that you need a reference card but doesnt state that the card should be a credit, gift card or similar. It needs to be more specific about what a "reference card" is.

Very accurate application !

I just wish I knew about this two weeks ago when I ordered some new glasses. Still, I recommend it for anyone who is shopping for glasses online and doesn't have a PD measurement already.

Though the credit card auto mode resulted incorrect results, after the manual adjustment (card edges and eye pupils centered) produced correct results.

In theory this could translate your 3D head to a 2D image and make an accurate measurement. BUT, you have to hold your head, camera, and credit card in just the right position and angle. And you can't. Not reliably. BUT...you could check your results with a 99 cent ruler to know if you were doing it right. Better just use the ruler and call it a day. "OK Google, how do I measure my pupil distance with a rule?" Wow, that was easy. Why did I blow $2 and an hour trying to get accurate results with this app?

However, it needs to be able to open existing pictures for remote measurements. This would be an easy feature to add, and would allow for easy lens fabrication.

I am not going to complain about the auto detection but I will take issue that the app appears to have a hard written orientation for the camera. Unfortunately, this meant I had to try and take my picture with my nexus 6 while my face was upside down. Lack of proper zoom, not counting the little pip with incremental swipe adjustment, also meant that an accurate measurement was not possible. Even the magnification pip moved in too large of increments to be accurate when making manual adjustments.

Complete rip off. Don't pay or download. Junk!

Doesn't work

What a waste of $1.99 , such a waste !!!!

Doesn't work

Using a 5x and the developer of this app obviously hasn't upgraded their camera API, as it causes the pictures to be upside down, which proves the app to be pretty useless. Got it to work on front camera but given the position of the camera on the phone (top left) I have trouble getting it to detect my pupils and where app isn't helpful

I respect the idea and the work that was put into it but it's way too inconsistent to be trusted. Never found my pupils and using manual mode was very difficult for me. It's easier and more accurate to just use a ruler and have someone measure the distance while you focus on an object.

Unfortunately this app didn't work for me....nothing is straight so the measurements are off.

Keeps not detecting pupils. Manual adjustment does not have save button. Uninstalled.

Not convinced this is 100% accurate. May have been my lighting.

I measured 5 times at 5 different result. The grids on the screen would not line up would not stay in place and were extremely hard to see. waste of my money can I get a refund?

Needs an option to take the photo via portrait mode and the zoom option is hardly visible

After trying at least 15 times taking a picture of myself in different bright rooms, I still couldn't get a picture where both the pupils and the creditcard where recognized. This was quite frustrating. Then I went outside and tried it again, this worked much better and gave pretty consistent measures. Since I rather have an app that's a little difficult to work with but precise and since there are not many online alternatives, I rate it 4 stars. However, be prepared to try it a couple times outside.
