View Full Version : What's your PD (Pupillary distance)?

As a playful experiment, please provide your PD along with your ethnic-background.

In case you haven't seen an optometrist, it's fairly simple to measure on your own:

As an experiment, I'm curious to know the average PD on the forum and see if there's any wide variation by population/ethnic-background.

Feel free to share any papers comparing global populations; I found a few online but none so-far pertaining to Nilotic-related populations. I'm guessing the PD average among certain Central-East African pops might be slightly higher than the customer-base of this online North-American based retailer from where I recently ordered a new pair.

Apparently mine was so uncommon (72mm) that I got an email back after placing the order asking for reconfirmation of my prescription details "... Note that the average PD is between 57 and 65 mm."

About 60mm, but I will measure at other times as well, when I find the look in my eyes to be different. I assumere the pressure behind my eyes isn't always the same and it seems to affect my view fiel. So the position and distance may vary very slightly, altho I have no idea such a thing is even possible.
