Most VR goggles eventually cause pretty significant eyestrain due to vergence-accommodation conflict [1] and other issues all of which get significantly worse the closer to the user the virtual objects are.

Apple's display is, I guess, in best-of-class, but they have no special sauce at all on this, and no physical IPD adjustment at all, and so this device as previewed is basically only useful for media consumption and maybe something like a telepresence meeting, albeit not long duration. Without controllers it's unlikely to even work well for most games.

Basically this is the best of a huge crowd of not very good VR helmets with probably industry-leading AR camera-based passthrough.

The Vision Pro demo clearly showed physical IPD adjustment multiple times.

IPD isn't that, they're talking about focus. All current VR headsets are focused at a fixed distance, typically around 2 meters away though earlier headsets focused to infinity. Anything outside of the 2m distance can look incorrect and it causes visual weirdness like depth of focus blur to instead look uncannily sharp.

Not fixable without varifocal lenses which adjust focus depending on what your eyes are looking at.

No I'm talking about IPD. Maybe someone else is talking about focus?

In the demo they showed a break out of the device which showed adjustable IPD width, with the displays sliding on little rods similar to many other HMDs.

My mistake, missed their reference to IPD.

I think it's automated? I guess with the eye tracking there's data for it to be able to center them.

Where? The lenses are clearly in a fixed location in all of the photos shown.

You mean like screens already cause issues to our eyes?

We don't have screens strapped two inches away from our eyes.
