I really wanted to try this and compare how accurate it is to what I got from my optometrist before I purchased a nee pair of glasses. The app can scan everything fine with my camera lenses, but as soon as I put it through my glasses, it tells me my camera is too blurry. I spent half an hour cleaning the lense and trying different lighting but could never get it to work. Perhaps i could have gotten it to work with a different pair of glasses, but then I wouldn't need this app.

10/10 - I couldn't find a mm ruler on hand, and I was actually having a hard time measuring to begin with. I almost gave up til I saw this app. I scanned three separate times, and two were the same, and the other was extremely close. Not sure if I would've figured it out without this. It is super easy and doesn't even take 5 minutes. For those worried about using your credit card, I just used my license and it worked fine. Will be back to this app for sure!

Doesn't work. On laptop it is unable to recognize the dots on the screen and keeps prompting. *Edit - this was attempted in various lighting conditions with no backlighting and repeatedly cleaned lenses. If the app gave some indication of what it could recognize and what it couldn't, the usability would greatly improve. At one point the app told me I was too close, immediately followed by I was too far away without me having moved

It seems like your device had some focus problems which are affected by lighting conditions and how clean your camera lenses and glasses are. Please make sure you clean the camera lenses and your eyeglasses before starting another session. We would recommend performing the scan in a well lit room with no bright backlights or screen reflections.
