Pupillary Distance/ PD / PD Value / or inter-pupillary distance (IPD) is the distance between the centers of your pupils. It is measured in millimeters & plays a vital role in making your prescription eyewear. On average, this distance is 63 mm however, even slight deviation of the pupils can result in problems with vision.
Broader PD Range:
For Men : 53 mm to 77 mm
For Women : 51 mm to 74.5 mm
Each pair of prescription eyeglasses has an optical center which is supposed to align with the center of your eyes i.e. the pupils. If even one of the two optical centers is not aligned according to your pupillary distance, you may feel discomfort while wearing your glasses and find it hard to focus on things. Wrong PD can lead to headaches, fatigue and even eye-strain. It is advisable to get to know your PD from your optometrist/optician at your eye test for a perfect pair. You can also find the same with the help of the below mentioned methods.
Methods to measure your PD
There are two methods to find out your Pupillary Distance:
Binocular PD (Single PD) : Distance between your two pupils.
Monocular PD (Dual PD) : Distance from your nose to pupil of either eye.
Let’s explore simple ways to measure your PD Value yourself.
If you’ve never faced any vision misalignment issues with your current glasses, you can use these to find your PD.
What you need: Ruler & a marker
What you need: A mirror & a ruler
If you already have a PD, look for an abbreviated “PD” column on the lower part of your prescription slip. If there are two pupillary values in your prescriptions, you might have to measure the distance between each pupil to the center of the nose bridge individually.
In case your PD measurement is not coming out right, you can also take help from a friend or visit your optometrist / optician to get your exact Pupillary distance.
