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 !
Very accurate with the new version. Makes for easy glasses buying. 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.
Thanks This app is very well done. My lighting wasn't so good and I did have to use manual mode, but it allows you to really fine tune it. I'm going to trust the accuracy and went ahead and ordered. The only problem was that I had to scan 3 credit cards because I kept dropping them in the toilet while I was peeing and didn't want to pick them up yet. Do not use this app while peeing!
No pupil recognized 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.
Great product Though the credit card auto mode resulted incorrect results, after the manual adjustment (card edges and eye pupils centered) produced correct results.
