But don’t worry—getting your pupillary distance isn’t as complicated as it sounds. We’ll explain what a PD is and why it’s important when selecting the right glasses for you. You’ll also find out how to measure this important factor, so you can get those glasses shipped out in no time and look fabulous while doing it!

What Is Pupillary Distance?

You may have heard of pupillary distance (PD) before, but what does it mean? In short, pupillary distance is the distance between the centers of your pupils.

For most adults, pupillary distance is between 54-74 mm. The PD of kids’ typically falls between 43-58 mm. The exact PD measurement is what’s used to determine where you look through the lens of your glasses. That way, glasses will be customized to fit your individual needs and preferences! To make sure you get an accurate reading, it’s important to measure by an optometrist or a reliable optician.

Why Is Pupillary Distance Important for Glasses?

Do you want to make sure you get the clearest and most accurate vision when looking through your glasses? Then you’ll want to know all about pupillary distance (PD), the key measurement used to determine where you look through your glasses.

PD ensures that the center of each lens of your glasses goes directly over your pupils—which is very important in order to ensure good, clear vision. That’s why most opticians will ask you for PD when you’re getting new glasses, whether they’re prescription or non-prescription ones.

Another advantage of knowing your PD is that it allows you to find the right frames for yourself. With this measurement in hand, you can find a pair of glasses with lenses that are positioned properly for your face and eyes. This means that not only will the frames fit well, but also that your vision will be crystal clear when looking through the lenses.

How to Measure Pupillary Distance at Home

If you’re looking for an accurate pupillary distance measurement and would rather do it yourself, you can measure your pupillary distance at home with a few simple steps.

First, stand 8 in. away from a mirror and make sure your eyes are parallel with the mirror’s surface. Then, hold a ruler against your brow and align the 0 mm mark with the center of your right pupil. Close your right eye then align the ruler’s 0 mm with the center of your left pupil. You’ve just measured both eyes simultaneously! Measurements are usually given in millimeters (mm).

Remember, when choosing the perfect pair of glasses, accurate pupil measurements are essential to ensure that you have sharp vision through each lens. That’s why it’s important to either have this done by an optometrist or do it accurately yourself at home!

Pupillary distance is an important part of making sure your glasses fit your face just right. Knowing your pupillary distance when shopping for glasses will ensure you get the perfect fit. Not only that, but it can help you get the perfect look for your face shape.

Finding the right pupillary distance for your glasses can be a bit time-consuming, but it’s definitely worth it.
