There are 2 types of PD Measurement—one for Distance and one for Reading.

We cover both types of PD using our printable downloadable PD ruler.

Make sure to print our downloadable PD ruler here:

Here are the steps you should follow:

How to measure a friend's distance PD:
====================================
1. Sit opposite your friend at arm's distance apart.
2. Fold the PD ruler to the "using a friend" side.
2. Place the PD ruler and align the zero with your friend's right eye.
3. Close your left eye and look directly into your friend's right eye. Your friend should look into your open eye.
4. Note the measurement directly over your friend's left pupil in millimeters.

How to measure a friend's reading PD:
====================================
1. Sit opposite your friend at arm's distance apart.
2. Place our downloadable PD ruler on the bridge of your friend's nose.
3. Your friend should hold a pen around 30cm (8in) in front of their face and focus on it with both eyes.
4. Note the measurement from the center of the right eye to the center of your friend's left pupil in millimeters.

We don't recommend using a mirror to measure your PD by yourself, as it is not the most accurate, but here are the steps in case it is the easiest method for you.

How to measure your PD at home using a mirror:
=====================================
1. Fold the PD ruler to the "using a mirror" side.
2. stand about 8 in (30cm) away from the mirror.
3. hold the PD ruler above your eyes with the zero directly above your right eye.
4. Close your right eye and read the number directly over the center of your left pupil. That will be your PD.

I have never seen the PD on a prescription - mine or anyone else’s. If they include it, they know you are going somewhere else to get your glasses.

[remainSOLID]

Her voice is hella soothing. Very informative too.

[gebusome]

Me doing this: "About 40-80mm give or take"

[portersblackboard]

This is super helpful! This is the first time I have seen a video that explains that your reading PD is different from your distance PD. I wish I had know that a few years ago. I have probably blamed online retailers for my prescription not being quite right. And I too have never seen a PD on a prescription. Now it makes sense why my distance glasses are never quite right,

[davidmenke]

OMG I want this lady to help me with everything in life! So sweet and nice, I bet she don't judge people for not knowing how to do stuff.

Mine said 80 and then when I typed it into the online website as 79 they said “this isn’t normal pick another number”

[strikevyyper]

Your voice is soothing for the ears, your friend is soothing for the eyes...who is she? she is gorgeous!!!

I've been wearing glasses for years and PD has never been included on any of my prescriptions. Information like this is withheld & the industry ensures that clients are never educated on these simple but very important matters on their own eye health which could be critical in the long run crippling clients' independence. Money and manipulation is a heck of a thing; how sad these businesses are. Oh Sigh

[DragonDoper]

I went to the opticians and asked them if they could measure my PD, they refused because they new I wanted to purchase my prescription glasses online for less than half the price they we're going to charge me, with the frame and lenses, they we're charging me £550 went online and got it for £220 don't get ripped off on the high street, daylight robbery!!!!

[bebesitab]

Thank you for this video it was very helpful👍 I was struggling a lot trying to order my glasses online cause I couldn’t find my pd but the ruler you linked In the description was very helpful also so thank youuu !

[LifeofaFatMan]

Thank you for the information. I now better understand PD and how to acquire my personal optic statistics.

[Xavird]

i need this lady's IG lol her voice its so calming

[nexttvc]

WOW very helpful and simple and beautiful. Thank you

[tashaleeann]

Except the print out on the website is incorrect. The 0 is over the right eye.

[te]

u gotta use a friend for a lot of this stuff...i don't have any.

[kern]

I had to watch this 3 times, too distracted by the gorgeous speaker the first on lol

[cruisey]

this doesn't make sense when using the mirror. I can't center the zero over my left pupil because the zero is on the right side when I hold it up in the mirror. And I know I'm holding it right cuz I can read numbers and the eyebuydirect logo. lol

[shaggy]

Finally a fucking useful video, thanks for existing!

[georgefaulk]

The girl getting the PD measurement is

[simonejones]

Anyone else here because their eye doctor charges extra to measure you? 😂
