I haven't found anywhere on the internet yet, a detailed guide to the Pimax Play software...if one exists, then I would be very grateful for the link!!

But in my original forays into the menus of Pimax Play, in the 'Advanced' page I noticed - but then promptly forgot they existed - Right and Left, Vertical and Horizontal IPD Offset sliders.

Scroll forward to now, with correct VR image distance corrective lenses from VR Optician, and a clarity of VR view beyond my wildest dreams, I was aware that my left eye was often spot on but the right one not quite.  If I moved my headset a touch to the left and right just a mm or so, I could get the same spot on focus in the right eye, but had now lost it slightly with the left eye.  Changing the IPD didn't help because the mask nose scoop is designed to keep the headset itself in a repeatable position on your face, so you got one eye or the other in focus.   So, clearly, one of my eyes is at a slightly different position from the centre of my nose than the other (which also probably explains the somewhat hurtful comments that MrsAJZip makes about my appearance 😆  ).

And that made me remember that 'Advanced' page.  Was it possible that, within a general IPD setting using the headset roller wheel, you could move the left or right IPD electronically and independently??

Well - I experimented, and I reckon that's exactly what it does.  With the right eye IPD slider moved to +1 (ie presumably 1mm further to the right) it seems to have brought that eye into perfect focus without affecting the clarity of the other eye :

   

 

Placebo or does anyone know if it actually does do this??  Whatever -the visuals are even better that they were before, whether in my head or in reality.  Happy chappie!  🙂

Hmmm.. ive seen the adjustment sliders too but unsure of how to use them... actually, im not sure which IPD setting to use...

Using the phone app, my far IPD is 62.5mm and the Near IPD is 60.0mm

Right PD is 30.8mm and Left PD is 31.5mm

What now do i do with that info? Which to choose from?

The IPD offset is a bit more complex compared to the default IPD settings. It allows for fine-tuning the IPD both horizontally and vertically. Since each user has a unique IPD (assuming the left and right eye distances are the same), you may need to adjust the offset if that's not the case.

This process will require incremental adjustments to find the optimal setting for your eyes. Unfortunately, I can't provide specific recommendations for this.

You may want to check out this video; it could offer some helpful tips.

But just to check,  @Calvin-Pimax - the IPD offset does operate with the Crystal Light as well as the other headsets that run on Pimax Play?  If so, that is brilliant!!  That is a very advanced facility for a mid-priced headset.

Yes. It does work.

That's tremendous!

Do we tune the headset for 'Near' or 'Far' IPD settings as reported for the IPD apps when we scan out eyes?  Thought I'd get official word since we're on the topic.🤔

I had to repost this. Typing while holding a conversation at times doesn't lend itself to the best results.🙃

Honestly, it's tough to pinpoint the perfect IPD setting for everyone, as it can vary based on individual eye differences and how they see in VR headset. Personally, I find a middle-ground value works well. I focus on an object about 1-2 meters away and adjust the IPD accordingly.

I gather the IPD software adjustment is moving the panel image slightly rather than the physical IPD adjustment which moves the actual lenses.

That's not what I'm asking.  The two IPD applets I used distinctly show where the IPD setting should be for 'Near' or 'Far' sighted adjustments.  For me Near would be 33.6 and far is 66.0.  This is very important as the CL screens are so close to our eyes.  Eye strain can be a larger problem if we set this wrong.🫤

Hi Dillon

There's something wrong in that result. 

If you think about it, that result has to be wrong.  The numbers are the mm apart of the centres of your pupils.  From your results, the centres of your pupils when you are looking straight ahead (which is what you are doing when looking at a far distance) are 66mm apart.  What happens when you look at stuff closer and closer is that your eyes both start swivelling inwards - and so the centres of your pupils start to get closer to each other.   But eyeballs aren't all that big and so even from looking at a distant object to looking at a book, that change of distance can't be more than a few mm. 

I'm using 'PDCheck AR' on the iphone at the moment and the results are very close to those at my recent eyetest.  It physically measures only your far distance IPD and then automatically adjusts that result (seems to be around -2mm) to give you the Near number.  It doesn't physically measure the near IPD.

 

In terms of your original general question, then I would personally start with the Far IPD result - but there is no guarantee that the Crystal Light IPD display is sub mm accurate anyway, and so there always is a bit of 'what feels more comfortable' tweaking that will be necessary. 

Interestingly, the Pico software has a set of concentric circles in their set up software that, they say, you can use that to visually adjust to your IPD setting (if your two eye views are offset, then the rings will be blurry, so you adjust the IPD setting until the circles become clear.  It's a good idea - but I personally could never get it to work.  I'm currently experimenting with some jpegs of varying thicknesses and density of concentric circles to see if the theory is right...but, so far, no 'I've Got It!' results 😀

Thanks.  What's interesting is I'm using 'PDCheck AR' and that's where I got my results.  So your saying used the 'Far PD' setting, correct?

Yes - I would start with that.

The other thing I tried (but actually got the same result) was hover my thumb over the 'Measure Now' button and look at something 1 metre (about 3.5') away and then pressed the button.  Theoretically, that is your IPD at a 1 metre.  That said, there will be an error factor in the app as well as in the Crystal Light IPD readout so, in any case, it's only a starting position to tweak from.

By the way - are you sure that the 33.6 number you got wasn't one eye?  It should give you:

The measured IPD (Far)

The measured IPD Left Eye and Right Eye (again Far) separately

The calculated IPD (Near)
