Quest 3 eye strain - but not on Rift, Rift S, Reverb G2

[Aerovenator]

A question for Quest 3 users: I had a Rift, Rift S and Reverb G2 before the Quest 3. I was able to use all of them without any problems or restrictions. However, when I use the Quest 3, I often have problems with my eyes afterwards, so they feel tired and sluggish. Focussing is more strenuous. I use the goggles with Kiwi Comfort Strap and AMVR Facial Interface, as I found the original head strap absolutely awful.  I measured the IPD with 2 apps on my mobile phone and adjusted it accordingly. Does anyone have any idea what is different about the Quest 3 in this respect? And what can you do about it? At the moment I only do short 30-minute trips. But that's not ideal.

Correct ipd setting? I noticed a difference in my tolerance to off-ipd between Pico 4 and quest pro. The QP appears much more tolerant to variations. These are both mechanical settings. The rift s is a software setting. I do not notice much difference when I change this too. Maybe the Q3 is very sensitive to ipd!?

Checked the IPD with 3 different apps. Results are between 63.5 - 64.5. So I set the IPD to 64. I also check the IPD setting before each session.

Go and get your ipd measured by a opthalmist

The focus depth might be somewhat different for the Quest 3

Optometrists IPD = 66 while app says 63.5 You can also use a chart in a program available via PC and use it through Steam or directly on a PC that lets you check vision via a Snellen Chart but not IPD. It says you cannot currently get 20/20 vision score due to current VR technology. The app is a bit dated, and he says he is working on an OpenXR version. I used it to check my FOV and vision comparing Rx inserts and position of my AMVR facial which has 3 positions adjustments for depth. I also get close enough to see clearly and then adjust the IPD and 63 comes in better than the Optometrists 66.

It's called TESTHMD and is available at itch.io for $4 usd. I load it to Steam and then run through Virtual Desktop. If you get this, use the 1.1a version. I tried running the version 2 from my PC and got several errors.

There is a guy on YT that uses it in his testing of VR and that's how I found it. If I can find one of his videos using it I will come back and link it.

Here are a couple YT videos on it:

Thanks for all the responses. 

I read here in another subforum that the Quest 3 has a shorter focal length (1.3m to 2m) compared to my old VR glasses. I have presbyopia with 1.0/1.5. However, everything is blurred with my reading glasses. My plan now is to test with 0.5 reading glasses that I can borrow from a friend. If that works, I would have everything measured by an Optometrist (incl. IPD) and then order the appropriate lenses

If you are into this for the long term it's worth investing in dedicated prescription lens inserts. They are about $60-70 or so.

That would be the plan

I find I can get my eyes a lot closer with px lenses. In the P4 and Quest Pro it gives a wider FOV.

[slughead]

I'd get an eye test.

Made an eye test today. The IPD result matches with the app results and for a distance of 1.3m I would need +0.5/0.25.

The Reloptics lens makers for VR can put a reading glasses effect based on a ratio they calculate, slicker than snot in the set I use.  I stuck with my opticians recommendation for magnification level already printed on the prescription data sheet.
