   As has been pointed out, it's the difference between pupil centers.

You can do this yourself by holding up a ruler (cm) and centering it on
your pupils. It's more dependent on who can line this up the ruler right.

   There's a hand held device the stores use. It's automatic and easy.
What that does is give you a different measure for each eye (which total
the overall PD). Perhaps you can get a reading, I did.

   I broke my glasses a while back and found the price for one lens was
huge, so I shopped online. I went here:

   My girlfriend looked at all the frames ,the $20 frames, the $50
frames and up to the $119 frames, and the one she liked best was $3.00.
Probably suits me. I believe the cost for progressive lens (standard
blanks) et all totaled out at $39. It took a couple weeks to get them.
I'm happy although I keep my $3 frames in the case when I'm not wearing
them.

Yeah, me too.

I'm surprised some enterprising people havent setup to just
do the PD for those who have the prescription but not the PD.

   The total is easy. I got mine spot on.

  I would think the way to set this up (L/R) is as a transparent rule.
The center of the rule would line up on the center of the nose, perhaps
attached to an old pair of glasses. You could easily photograph this
(set macro) and read the offset from the image review. Dead accurate, I
would think.

   I used a transparent ruler when I measured mine (total PD), the split
seems easy, even if it is off it is better than no offset.

   Hope this helps someone. It never occurred to me I could try this myself!

I didnt. I tried it myself and then found the PD on an old prescription, I was
out by 2mm


Havent tried that approach.


easy, even if it is off it is better

The form on most online forms only allows the total to be entered.


I might try it if I remember, since I have a professionally measured PD to
compare it with.
