After trying and sending back Varjo Aero, I want to ask who has big IPD and successfully use Crystal for longer playing sessions? Please somebody who has ipd 73+ mm write about your experience…
I have IPD about 74-75mm, and I use 8kx; my IPD slider there goes up to 70mm (written in HMD), and then it moves a litte more. I can use my 8kx several hours without eye problems.
Just for record, Aero has IPD up to 71mm, and they said people with 73mm can use it. I really do not believe that. I was crosseyed (a lot) since start, and also color shift was much stronger because of me looking outside of sweet spots. Pitty, as I mostly like it (except no audio, mic and hmd was hard to put on/off).
Ah my IPD is a pretty average 62mm so I can’t provide any insight here.
I do know a couple of high IPD users, I think about 72mm so I will ask them.
Fwiw, aspheric lenses are a lot more forgiving with IPD than fresnel and on the Crystal I don’t notice any signiticant change in image quality with +/- 2mm IPD adjustment but that might not translate to the extreme higher end. If I hear back from anyone then I’ll let you know. Might be best to post on the Pimax reddit also, or the discord, they are a lot more active.
Mine is 69.5 and i’ve had no issue with the Aero, 8KX, or any of the 10 headsets i’ve owned in 9 years of using vr. An interesting thing i’ve noted with my Quest 3 is that the ipd slider i can basically set at any value and the display doesn’t change much if at all, i know if i did this on other hmd’s i’d be going cross eyed. Thankfully it is a clear non cross eyed image i’m experiencing at any ipd on the Q3.
My first VR HMD was oculus CV1. I had to put some rubber eraser between the lenses parts to have them separate enough for using.
Then I had 5kx, and 8kx - in booth I was pulling that dial for IPD to maximum and beyond they didn’t broke, and I was suddisfied with ipd adjusment.
Beside that I tried 3 other HMDs, all 3 were not suitable for me;
Playstation vr version 1, quest 2 and varjo aero.
I do thik that my IPD is about 74-75mm, even if my measurement in glases store was 77.5mm on looking to infinity.
With 77.5 I wouldn’t be able to use any HMD
I tried meta quest 3; IPD was too small for me, headstrap was nightmare, but I also had problems with facepad; it was pressing my left and right side a lot. It is designed for small IPD and small head too.
