Well, I don't believe a half a millimeter is going to make much difference, in either direction.
If it was me though, I'd put my correct PD in the "extra info or "remarks" area when placing an order. Especially if I had my monocular PD ( the distance from center of nose to center of each pupil ). I had my PD measured once, and I was told it was 67 (R33.5/L33.5) and had glasses made with that PD. Later, I had my PD rechecked three times due to getting a pair of bad progressives, and it was a 66.5 (R33.5/L33.0) all three times. The pair of PD 67 progressives (the good ones) were perfectly fine. I didn't notice any problem at all, even with the narrow intermediate corridor, which is where I think it would be most noticable. -=# Friewalker #=- On Mar 11, 2:20 pm, Sean <[email protected]> wrote: > I know that pupillary distance isn't an exact science, and that a > small deviation will be okay.
