For plus lenses, which PD do you use ?
« on: January 29, 2014, 07:11:52 PM »
Can't find any info on what pupillary distance to use with plus lenses (normal computer use)
Curious what PD other printpushers use

Atm my PD is 66/63mm far/near, I use 64mm lenses as the monitor is farther away than say if I was reading a book

From what I understand PD doesn't matter much until you get to higher power lenses.
But wouldn't eyes also converge more if you use higher plus ? (thus requiring higher PD ?)

Edit: Ah my bad I've mixed between convergence and divergence.

What I meant was higher plus causes divergence of the eyes.
And therefore it makes sense a higher PD would be preferable no ?
(higher PD = works better with higher divergence)

Hi Svartberg,

Since you asked the question - I use, off-the-shelf "readers" for my print-pushing use  Thus I accept the standard PD, and have no problem with it.

If your plus is intended only for "close work", just take your self-measured PD, and subtract 3 mm.  Then order your plus lenses from:

There lenses are of excellent quality - and you get the glasses in two weeks.  The video on how to order - are excellent.  I would never buy a lens from an OD - ever again.  But I would get the prescription from them - just to check.

Best,

Cheers for the reply OtisBrown

Sounds like I'll just use my near PD from now on then

I ordered mine from goggle4u, got quite a collection of plus lenses by now ;)

I did a lot more reading, the consensus online seems to be
Near PD - 1 feet away, for books, newspapers, etc ..
Mid PD - 2 feet away, for computer etc

So I reckon it was a good call to pick 64mm instead of 63mm.
Either way, most people agree the 1 mm difference in negligible as it is, just nitpicking here.

Also from actual experience, some notes to whoever reads this :
I've noticed a lot of difference between 67mm PD and my corrected 64mm PD, to the point I couldn't wear the 67mm ones.
I've also had minor yet noticeable difference between 32/32 PD and my corrected 31/33 PD.
