Prescription Scanner

This is sorcery! I feel just like I did as a child when David Copperfield asked me to hold my card up to the television screen and guessed the suit and number. And then made the Statue of Liberty disappear. I ordered a pair of glasses from another company and tested this app to see if it would work or if I should go to an optician to check and ensure the correct prescription. This was SPOT ON in what I ordered. Even the Cylinder was perfect, along with my pupil distance given by my doctor. The axis was within 3-4 degrees for one of the eyes, but it was minimal one time. I tested this cauldron of spells three times and the second of three had one eye off by .25, but that was because I did a horrible job keeping steady when tilting my glasses. Make sure your steady and do it a few times to confirm. Sorcery I say....

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.

I was skeptical of this app. The idea that my phone camera could accurately tell me my prescription sounded ridiculous to me. I downloaded it anyway and did what it said and got my prescription. I wanted to order new glasses but I didn’t really want to use the prescription this app gave me because I didn’t trust it so I called my optometrist and had them mail me my real prescription. Then I remembered the prescription I got from this app and they are exactly the same! The only thing that was different was the axis measurements. I was super surprised how accurate it turned out to be. Doesn’t beat getting your actual prescription but it will work in a pinch.

Both my roommate and I had great hopes for this app. It started well enough. The scanner quickly and easily connected the cell phone and laptop. I got a credit card and began with the size adjustment. From here on everything began to go downhill. I tried the size adjustment using every finger and different positions. I even flipped the laptop onto its display to let gravity hold the card between the dots on the screen. This way it was far easier to keep the dots reliably inside the scanner. However, even after maintaining the dots and card in the cell phone scanner for more than 5 minutes the app was unable to adjust for size. Out of approximately 7 separate attempts to set up the app I managed to get through this step only once. The one time I was able to begin measuring the glasses it was extremely hard to keep the the glasses aligned in a way for the scanner to measure them. I think that the app has potential but it is too difficult to keep the computer display, glasses, and cell phone aligned long enough to let the app scan. I have yet to understand why scaling would take so long. One scan should be enough to determine the size of the card based on the 6 dots on the screen.

Alright, so I was hella skeptical of this app but I figured it was worth a shot so I took a chance and used this to figure out my prescription (since I am too much of a wuss to just call my Doctor). Anyways, I followed the instructions and got my prescription perfectly!! I did this process about 5 times just to make sure, because I’m personally very paranoid, but turns out I got the right prescription on the first try! Did get 2 duds on my quest with this app so I’d recommend you to test this out a couple of times. Other than that, it was an easy process and I definitely recommend this app!!
