How to Measure Pupillary Distance at Home for SpecTats Wearers
As a brand dedicated to those who see eyewear as an extension of their identity, we understand the importance of precise fit and comfort. So it’s important that you know your pupillary distance (PD) for when you order your SpecTats. If your eye doctor has not provided this information on your prescription, don’t worry. We’ve included a couple of easy ways to find it at home below. But before we dive into how to find your PD, let’s first go over the fundamentals of pupillary distance.
What is a PD?
Pupillary distance refers to the distance between the centers of your pupils, measured in millimeters. It's a crucial measurement for ensuring that the optical centers of your lenses align perfectly with your eyes, providing optimal vision correction and comfort.
Single vs Dual Pupillary Distance
Single pupillary distance refers to the measurement between the center of one pupil and the center of the other pupil.
Dual pupillary distance, on the other hand, accounts for the distance between the center of each pupil and the bridge of the nose.
Why You Might Have a Dual Pupillary Distance
Having a dual pupillary distance is common for individuals where each pupil has a slightly different distance from the bridge of your nose. Measuring the distance from both pupils ensures that each lens is customized to provide the most accurate vision correction possible.

Manually
Materials Needed:
- A ruler or measuring tape with millimeter markings - millimeters is very important!
- A well-lit area with a mirror.
- A steady hand and a little bit of patience.
Step-by-Step Guide:
- Prepare Your Tools and Space:
Find a well-lit area with a mirror where you can comfortably stand. Ensure that your ruler or measuring tape is easily accessible. Note: You can find a pupillary distance ruler online that you can print off at home - if you have a printer.
- Stand Straight and Steady:
Position yourself in front of the mirror, ensuring that your head is held naturally straight.
- Place the Ruler or Measuring Tape:
Hold the ruler or measuring tape horizontally against your forehead, ensuring it is straight and level. Make sure the markings are clearly visible.
- Close One Eye:
Close one eye and focus on the mirror. Align the zero mark of the ruler or measuring tape with the center of your open eye's pupil.
- Take the Measurement:
Without moving your head or the ruler, open the other eye. Note the measurement (in millimeters) where the center of your other pupil aligns with the ruler or tape. This number is your pupillary distance measurement.
Tips for Accuracy and Precision
- Ensure the ruler or measuring tape is held steady and parallel to the ground.
- Relax your facial muscles and maintain a natural, forward-facing gaze during the measurement process.
- Take multiple measurements to account for any slight variations, and then average the numbers out. So, if you take the measurement 4 times. Take each of those numbers, add them together, and then divide by 4.
- Enlist the help of a friend in taking the measurements to make the process a little easier.
