Ratings and reviews

Incorrect measurements despite several attempts. Went to a eye doctor for a proper measurement and this app was about 10mm off.. Waste of $8. Also a pain to use when you can't see the app. (While the setup boxes are bright, they are super thin, so when you have to take your glasses off for measurement, you aren't able to easily make out where to line up your head.. maybe make that a little bolder.

Works great. Got one number for 3 tries, then got a slightly higher number (1 mm higher) the 4th time after looking into the distance when taking the photos. Need to go read the directions again to see if I did it exactly right. Will update shortly.... UPDATE:. I didn't see instructions on how far to stare when taking the photo. So when looking at the camera, I got 66. When looking into the distance, I got 67. Seems pretty accurate to me. SECOND UPDATE: Thank you, GlassifyMe!!

Fairly accurate, but can be difficult in selfie mode. Luckily, able to use a friend and rear camera to make a bit easier. Since the selfie flips for alignment, can be harder to get the card straight and flat on subsequent tries. Kind of important since the card is used for the basis of the measurements. Getting the card straight and flat in the picture, as well as keeping your eyes open as wide as possible (think old Dracula movies) will improve accuracy since you control the outcome.
