WHAT IS PUPILLARY DISTANCE AND WHY IS IT IMPORTANT
Pupillary Distance (or PD) is one of the numbers that you will need to enter in your prescription while buying your glasses online. It measures the distance in millimeters (mm) between the centers of your pupils. It is important to have an accurate PD to ensure that you're looking through the correct spot in your lenses and have clear and the most accurate vision at all times. The average PD for adults is between 54mm to 74mm, whereas, the same for kids is between 43mm to 54mm. You can get your PD measured by an eye care professional or can also do it yourself by following the simple steps below.
STEPS TO MEASURE YOUR PD
Step 1: Get a Millimeter Ruler and a Mirror
Step 2: Maintain a gap of 8 inches from the mirror.
Step 3: Keep your face straight and place the millimeter ruler against your brow on your forehead.
Step 4: Close your left eye and align the zero of the ruler to the center of your right pupil
Step 5: While looking straight, close your right eye and open your left eye
Step 6: The "mm" line that coordinates the center of the right pupil is your PD
HAVING YOUR FRIEND MEASURE YOUR PD
Keep both eyes open and look straight ahead while your friend measures your PD. Have them put the zero on the millimeter ruler over the center of one pupil, then measure the distance to the center of the other pupil.
TIPS WHEN A FRIEND IS MEASURING YOUR PD:
1) Make sure they crouch/sit while your stand so they are not within your field of vision.
2) Do not move and keep your eyes as still as possible.
3) Do not look at your friend while they measure your PD.
4) Look above their head at something approximately 4 to 6 meters away.
