Calling ATOT optometrists. How to figure pupilary distance

[BKLounger]

So I am giving getting glasses online a try (just prescription sunglasses). I got all the other info from them. Sphere, Cylinder, Axis. But they didn't have the actual pupilary distance. All they had were the values

OD-34
OS-32
OC Height 12

How do i get the value of my pupilary distance using those values? From what i read pupilary distance should be something between 35 and 95. Anybody got any ideas?

Should be doable with a ruler and a mirror.

The eye doctor doesn't usually do this measurement - it gets done at the store.

Just go to an eyeglass store (Walmart or wherever) and ask if they will measure it for you. They have a device which looks like a pair of binoculars that you look into - takes just a few seconds. Go sometime that's not usually very busy and they'll do it.
