How to Measure Your PD At Home
Use this step-by-step guide to measure your pupillary distance (PD) by
yourself or with the help of a friend.
Having A Friend Measure
Your PD
If a friend is measuring your PD, keep both eyes open and have your friend put the zero on the millimeter ruler over the center of one pupil, then measure the distance to the center of the other pupil.
Have them crouch/sit while you stand so they are out of your field of vision.
Look above his/her head at something approximately 10-20 ft. away.
Keep your eyes as still as possible.
Do not look at the person measuring!
