Prescription Scanner 4+

Perfect

Absolutely nailed my prescription. A family member was having a hard time getting her prescription from her dr in order to buy a new set of glasses without setting up another pricey appointment - so I went digging around on other ways to get your prescription and stumbled upon this app. Tried it on my own glasses and it took a few minutes but came in perfect on my prescription for both eyes and pupillary distance measurement as well. An amazing free tool to have in your arsenal, and they don’t even force you to buy glasses from them - they list your prescription numbers right on screen once the measurements are done. Well done on one of coolest apps I’ve used, I might actually buy glasses from them when I need new ones just because I am so impressed.

Doesn’t work with large, hi-resolution monitor

Updated: changed rating from 1 star to 3. The problem was with my hi-res 32-inch 4K monitor, set to “larger size” text in the Macintosh display control panel. The app thought the browser window was too small when in fact it was large. By the time I made the browser window big enough so the app stopped complaining, it was so huge I had to hold my phone WAY back, and couldn’t hold my glasses half-way between.

When I switched to the MacBook’s built-in laptop display, it was fast and easy.

Original review: Spent 15 minutes, app simply didn’t work. First, it kept telling me to get the dots in the phone camera’s view even though they plainly were. Then it just couldn’t find my credit card even though I followed the instructions exactly. Finally got thru that, then a repeat of those failures as it tried to measure my glasses. After 20 minutes my arms were so tired from holding my glasses and moving them back and forth with no apparent progress I had to give up. Very frustrated.

Developer Response ,

Hey there! We are very sorry you felt frustrated with the app. Sometimes the camera is dirty and the app is not able to read the lenses. We suggest you to try it again by cleaning the camera and let us know if if works for you.

App and set up is trash

First off the process this app goes through to get you anywhere is terrible automatically setting the volume on your phone to 3/4 max is way to loud for you literally holding your phone. Second, you can not skip past the absolutely long winded instructions even when you have gone through them before. Third, the you have to go through several steps to get everything synced up, which is understandable, the app then has the worst response to everything it asks you to do. It literally repeated over and over and over “make sure the dots are visible on your mobile screen” meanwhile I sat there with the dots clearly visible in the cropped in area of the screen. When I managed to actually arrive at the screen to read my prescription it would again repeat the same phrase over and over and over and never went past this point. I made it to the prescription scan screen 5-6 times with the same result “make sure the dots are visible on your mobile screen”
