The approximate pupil center coordinates detected are:
Left pupil: (5, 232)
Right pupil: (624, 253)
Interpupillary distance (IPD) in the image:
≈ 619.36 pixels

Using an average human iris diameter of 11.8 mm as the scale reference:
Interpupillary distance (pixels): 619.36 px
Detected iris diameter (pixels): 232 px
Scale factor: 0.0509 mm per pixel
Estimated Interpupillary Distance:
≈ 31.5 mm
