This app is a simple tool to calculate the Pupillary Distance(PD) value that can be used when ordering glasses.
To determine this PD value User have to follow these steps:
- user take selfie with the phone's built-in camera, holding a standard size card - student card, credit card, etc. to the forehead.
- The application guides the user through OnBoarding screens before capturing the image, informing the user of the correct image acquisition process.
- The application then creates a "new measurement project" in which the user "annotates" the image by touching and dragging, places markers on his eyes and on the lower corners of the card. From the given inputs, the application calculates the pupillary distance using a mathematical formula, then the result is presented to the user on a Result Screen.
