I believ they are not obliged to give you the PD. So I ask.


But its so easy to measure your PD. Take a selfie with your smart phone
with a ruler held at eyebrow level.

Hi Bob

I have got SWMBO to do that. In fact I measure from mid nose to the
centre of my right eye, then double it. That's more accurate - for me.

Huh?

I measure my PD myself as well. But how is that method more accurate
than measuring the actual PD in full?
