Hi Guys,
I'm seeing conflicting PD for this type of lens. It is based on the manufacturer?
For a regular Distance/Reading PAL the Distance PD is used - standard. For the Intermediate/Reading PAL I see some say to use the Distance PD while others say to use the Intermediate PD. What is the optically correct answer?

PS - I know if we're making a Single Vision Intermediate (Computer) lens we usually reduce the Distance PD by 1.5mm. Is it the same for an Intermediate/Reading PAL?
