When shopping for eyeglasses or reading glasses, you must know how to measure your pupillary distance. It will help you decide where to place the lenses. You can use a ruler or even a smartphone camera to do this. The results can then be carried over to sunglasses and contacts.

It is vital to have accurate pupillary distances because they help make the lenses comfortable to wear. Measuring your distance accurately can help prevent headaches, eye strain, and incorrect lens placement.

You will need a non-permanent felt-tip marker and a ruler to measure your PD. Position yourself about eight inches away from a well-lit mirror. Close the left eye, and hold the ruler up to your brow line. Line up the 0 mm line on the ruler with the center of the left pupil.

When the PD is marked, you should move to the right to take a few more measurements. Repeat the process for the other eye.

Once you have done this, you can see how your distance changes over time. Most people’s PDs fluctuate from birth to age 19. Depending on your age and gender, you may try to find the exact measurement several times.

An excellent way to ensure you have measured correctly is to check with your friend or family member. They can also use a PD meter to measure it.

You can use a ruler or webcam if you don’t have a friend or family member. However, your eye doctor or optician will likely be able to do this for you.

Binocular PD vs monocular PD

If you’re shopping for glasses, you need to know your pupillary distance. It’s a fundamental measurement that will determine whether you’re comfortable with your new eyeglasses. A mistaken pupillary space can cause eye strain and headaches.

The pupillary distance can be measured using a ruler, a non-permanent marker, or a mobile phone app. It would be best to take several measurements to get a more accurate one. However, if you need help measuring your PD, ask a professional. The eye doctor can help you with this measurement.

For the right eye, measure from the nose’s center to the pupil’s center. To do this:

  1. Look straight ahead.
  2. Hold the ruler up to the browline.
  3. Align the 0 mm mark on the ruler with the center of your left pupil.

Measure the distance between the dots on your lens. Your eye naturally shifts outward when you’re looking at something far away. Look at an object at least 20 feet away to get an accurate reading. When you’re finished, remove the markings.

If you need clarification on the pupillary distance, try the EyeMeasure app. It’s free and available for iPhones and iPads. Or, try a millimeter ruler.

If you need a second person to help you, you can have a friend hold a ruler up to the browline. Make sure the millimeter line is at the center of the other pupil.

If you don’t have a prescription, you can also use a mobile phone app to measure your PD. However, you may need to provide a photo of your face.

You can also ask an optometrist to do this for you. He will be able to measure your pupillary distance accurately.

Far pupillary distance vs. near pupillary distance

There are several ways to measure your pupillary distance. You can find online tools or have an optometrist measure it. However, it is best to have your length measured in person by an eye doctor.

To measure your pupillary distance, close one eye and position yourself at a distance of eight inches away from a well-lit mirror. Then, open the other eye. Depending on your prescription, you may need to make multiple measurements.

Use a ruler or a pen to mark a millimeter line on the outer side of the right or left pupil. When you are finished, remove the markings and focus on an object ten to twenty feet away.

You can measure your pupillary distance home if you do not have a prescription. You will need a ruler or a non-permanent felt-tip marker. It can be a pencil or paper.

It is crucial to measure your distance accurately to avoid wearing glasses too close or too far from your face. Opticians can use a machine or handheld tool to measure the distance between the marks on your glasses.

You may also want to measure your pupillary distance if you order new glasses. Online stores often require you to do this. If you order from a retail store, your eye doctor can also give you a measurement.

You can also measure your distance at home using a webcam. However, keeping the camera’s angle straight would be best.

If you don’t have access to a mirror or an optometrist, you can measure your pupillary distance with your smartphone.
