How To Find Pupillary Distance Glasses
The average pupillary distance for adults is between 54 and 74 mm. Knowing this number means we can make sure you’re always looking through the correct part of the lens, and we can’t actually make your glasses until we’ve got your unique pd.

How to find pupillary distance glasses. The pupillary distance (pd) is the distance between the centers of your pupils in each eye. Most pds are in the range between 55mm and 72mm, though some people can have smaller or larger pds. When we need to get a new pair of glasses, our doctors need to measure the distance between the centers of the pupils, also called pupillary distance.
A ‘dual’ pupillary distance number is the distance in millimeters from each eye’s pupil to the center of your nose. Pupillary distance what is my pupillary distance (or pd)?. Dual pd, or monocular pd, consists of two numbers and is the distance between the centers of each pupil to the bridge of the nose.
If you don't need glasses, there's no reason to worry about what your pupillary distance is and how it works. A single pd will be just one number, while a dual pd will have a number for each eye, marked ‘right’ and ‘left’. Pupillary distance (pd) measures the distance between the centers of your pupils.
Whilst looking in the mirror, ensure the pupillary distance ruler’s zero is aligned with your left pupil. If you are farsighted, or are measuring for reading glasses, you’ll need to subtract 3 mm. This measurement is required to place prescription glasses orders.
But if you're hoping to lean on glasses to help you see clearly, it pays to ensure you have the right data at the right time. Without moving the ruler, close the left eye and record the measurement from your ruler’s zero to the right pupil. Follow these easy steps below:
Look straight ahead into the mirror and position the ruler over the bridge of your nose. Dual pd is usually written in the following notation: Remember, these are averages so your number may not fall within these parameters, but should land somewhere between 41 and 80 mm.
Your pupillary distance ruler can be any millimeter ruler. Pd (pupillary distance) is a measurement of the distance between your pupils. The pd is required so that we can make your glasses with the centre of the lens sitting directly in front of your pupil.
For a pair of glasses to perform as well as possible for you, the lenses need to be made to match this distance between your eyes, so that the centre of each lens aligns with the centre of your pupils. Your pupillary distance (pd) is the distance between the centre of one pupil to the centre of the other pupil (the blacks of your eyes) measured in millimetres. Measure the distance from your right to your left pupil.
Pupillary distance is essential for crafting prescription glasses because it helps us know where to place the center of your vision on your lenses. Your pupillary distance determines where your “optical center” lies. Pupillary distance, sometimes referred to as pupil distance or just pd, is the distance between the center of each pupil and the bridge of your nose measured in millimeters.
Measuring a friend’s pupillary distance to measure someone else’s pd, have them look at something around 20 feet away from them with both their eyes open. An adult’s pupillary distance may range from 54mm to 74 mm. Close your right eye, and align the ruler’s zero to the center of your left eye.
Look straight ahead, close your left eye and open your right eye. Just have your prescription ready and make sure your measurements are. With this measurement we can ensure that the optical centers of your lenses are aligned correctly with your pupils to give maximum comfort and effectiveness.

This distance is your pd. This will likely be the least accurate solution, but you should be able to get a reasonably precise read. Another method for checking your pd is using your existing glasses.
For this method, you will need your existing glasses, a felt tip marker and a millimeter. Your pd, or pupillary distance, is the measurement between the centre of your pupils.it’s measured in mm and very important if you have a strong prescription or are ordering varifocal lenses so that the optical centre of the lenses can match the wearer's pd for best vision. Read below to learn how to calculate near pd for reading glasses.
In some cases, this distance may be measured incorrectly, and there are a lot of things that could go wrong if these measurements are not correct, or off even by the smallest number. This measurement is used to determine where you look through the lens of your glasses and should be as accurate as possible. The millimeter number that lines up with your left pupil is the measurement you want.
Distance pd can be used to order any type of prescription glasses except reading glasses. It is required to craft the focal point in the eyeglasses which lead to clear vision. Whereas the pupillary distance of kids lies between.
(some prescriptions may have ‘od’ for the ‘right’ eye, and ‘os’ for ‘left’ eye.) Find out more about what pupillary distance is, how you can measure your pupillary distance and what you can use your pupillary distance number for. Pupillary distance means the measurement of the distance between the centers of the pupils of both eyes.
Using a ruler, line up the 0mm mark with the centre of one pupil, then measure to the centre of the other. For kids, the average is between 41 and 55 mm. The average puplillary distance for men is 64 millimeters and 61.7 millimeters for women.
Starting with the right eye, line up the zero end of the ruler at your pupil; One way to double check is to make sure you fall somewhere in the typical pd glasses range. Your pupillary distance (pd) is the difference between the centre of your right pupil and the centre of your left pupil, measured in millimetres.
This measurement is an important piece of information that we need to deliver the very best vision in your new glasses. Pd (pupillary distance) pd is the distance measured in millimeters (mm) between the centers of each pupil, and is used to make prescription glasses.
