You could also have your son hold the millimeter ruler in front of your pupils (remember it's center to center). Another way is to wear a pair of glasses and make a mark with a felt tip pen at the center of each pupil, then measure the width between the dots. If you measure all 3 ways and come up with similar PD's, it's probably right. One or two millimeters variance is not a big deal.
My PD is 60 and I have an average width face, so 53 sounds normal for a narrow face.
