Please go back to the drawing board! I appreciate the idea of this app. Today is like pulling teeth to get these measurements from any establishment that sell glasses. Online companies have no overhead so is far more economical. This app could be a great success but falls way short on accuracy. 9 measurements all averaged compared to an actual measurement by the doctor was 7mm off. Needs a lot of work. I suggest pulling it off play store completely.
Horrible Different reading with every picture, by a huge margin. I used the same card for several pictures & then switched to another card for several pictures & every measurement was hugely diffrent! DO NOT WASTE YOUR MONEY!
Does NOT get your PD value correct This app does NOT get your PD value correct ... I've tried multiple times, but it gave me the numbers from 61-63, which are incorrect! I know these values are incorrect because I went to an eye doctor which measured my values as 71! Absoloutly do NOT recommend this app, because when buying glasses you MUST have the PD value correct.
Don't download Don't use, it's was very difficult to get an accurate reading. . . .Very very fiddly
Terrible I can't place the marker because I can't see where I am placing it.
It Works!! (But needs 2 people) On HTC Desire. Requires good lighting for the photo - especially if your eyes are darkly coloured. The card needs to be a colour that gives good contrast with it's magnetic strip. It's best if you have someone to take your picture, otherwise it can be very difficult to use. I have successfully purchased glasses online using the 'PD' measurement from this app.
