FAQ to Measure Pupillary Distance
How do you measure PD for progressive lenses and bifocals?
For bifocal and progressive lenses, two PD values are needed. In these cases, Yesglasses recommends getting your PD directly from your eye care professional.
What is the average PD?
The average pupillary distance for adults is between 54-74mm. The average pupillary distance for kids is 43-54.
How do you measure your PD by yourself?
You can measure your own PD with a ruler and a mirror. Be sure to note which eye you are measuring, read the ruler properly in your reflection, and take multiple measurements to check for accuracy. We highly recommend letting Yesglasses measure your PD for you!
Can I measure my PD with a webcam?
When choosing to use a webcam to take your picture, be sure you are in natural lighting and that your picture clearly shows your pupils. Follow our instructions to use a credit card for measuring the distance and send us your picture.
Does Yesglasses measure PD online for free?
Yes! Our online PD measurement tool is entirely free and even gives you access to discounts while shopping with us.
How do you measure your PD without a ruler?
An easy way to measure your PD is with a credit card. Follow our instructions to take a picture of yourself with a credit card, then submit your picture and we’ll do the rest!
How do I find my PD on my prescription?
In most cases, your optician will include your PD measurement in your prescription after the eye examination. If not, just ask for it! Your PD will be listed in a section separate from your eyes’ prescription either as two numbers for each eye’s distance from your nose bridge or a total number for the distance between your eyes. Give them a call if you’re unsure, or email us your prescription and we will take a look for you!
