You can attempt in taking pupil images with your smart phone for assessment but we cannot guarantee acceptance for assessment. Try reviewing this youtube tutorial or more complex method for taking images of the eye.
Processing smartphone images for assessment does not guarantee that final assessment results will be approved after final evaluation. There are instances when submitted images using various degrees of pixel size and cannot be used for assessment.
Using 640X480 is the most recommended resolution for taking images of the pupil. Other resolutions can be used but should be multiples of 640X480, for example, 1280X960, 2560X1920, 5120X3840,etc. If resolution is not multiples of the standard 640X480, there is the possibility of incorrect compression of images leading to oval-horizontal pupil and false positives which are rejected.
At this time we are attempting to correct image resolution inconsistencies.
To understand more about correct image resolutions, please refer to the sample chart below:
