Seriously Amazing!

I’m a hard sell on lots of things, but this app is seriously amazing! Was recommended to us an optometrist who said she’d never had problems with any of its measurements. Mom ordered glasses online with the PD measurement from here & they’ve been great. Just used this app to read my Rx off my current glasses & it’s spot on iirc! Definitely exceeded expectations :)

Thank you so much for your review!!!

beware of data collection policy

To measure, the app requires a magnetic strip card. In most cases, people will use credit cards found in their wallets. By virtue of taking an image of the card, the app collects your credit card information, partially or fully. It is not clear if the images used are deleted or retained, and if the image scanned are used to extract additional information (e.g. name, card number, exp date, institution, etc) beyond distance/scaling measurements. Normally I would think about these issues before using any app, but now I am regretting having used it knowing a picture of my credit card is on their servers.
EDIT: the developer policy states the company will make “reasonable efforts” to apply an obfuscation algorithm on the image for details. It is still not clear if the initial raw images are saved somewhere and how good this algorithm is.
2nd EDIT: developer response is reassuring.

Thank you for your feedback. GlasssesOn's mission is to make vision care accessible and affordable. Accuracy is our #1 priority. To achieve the highest level of accuracy we ask the user to use *any* magnetic card (e.g. library card, metro card etc...). We do not collect, track or identify any data on those cards. We respect our users' privacy and take multiple steps to ensure it. Thank you again for taking the time, you may contact us directly at with any additional questions and concerns. The 6over6 Team

It works but MAJOR concern...

DON’T USE CREDIT/DEBIT CARD, PICTURE GETS TAKEN!! I used this to test against another pupillary distance measuring app and pretty much got the same result which was great. I found that I did not need to use a magnetic card to get the result, I just used a paper gift card. My concerns come from the end just before it gives the PD result, it asks you to smile and then takes this picture which you’ll never find or see. I was smart enough to have my card turned around with no information showing but what was the picture for and what if I wasn’t smart enough to turn my card around? Why do you ask for a magnetic card which most will choose a credit/debit card with the number indented on the back? What information is this company storing and how are you using it? HUGE CONCERN...
