what is average pd range
Measure PD your self. 1. Place a mm ruler directly under the center of your right or left pupil so that the ruler is horizontal. Stand in front of a mirror, or ask someone else to measure for you. 2. While looking straight ahead, measure the distance from the center of your left pupil to the center of your right pupil. 3. Repeat a couple of times for accuracy and use an average for your final measurement. *Note that the average PD is between 57 and 65mm.
