You’ll just need your phone and a card with a magnetic stripe. # show the output image with the face detections + facial landmarks Simply follow the steps below to take a selfie and our team can calculate your pupillary distance.

My code is below(because of many attempts with different strategies and parameters, my code is not clean yet. The pupil is the dark circular opening in the center of the iris and is where light enters the eye. Does anybody have any suggestion about which library to use? Or any suggestions about how to proceed for measuring distance from an image with a reference object in it? A pupillary distance measurement, also known as an interpupillary distance measurement, is needed to set your glasses lenses within your eyewear or eyeglasses frames. 2000 Kanellopoulos & Asimellis 2014). I have tried some libraries(such as opencv and dlib) but failed to achieve that precision. The reported transient miotic effect of cataract surgery on short term is consistent with one previous study (Hayashi & Hayashi 2004).Yet, other studies have reported decreased pupil size up to 12 months after surgery (Komatsu et al. I'm considering to use a credit card held on forehead so that distance in pixels can be converted into mm.
