One thing you've really got to watch out for (and that Meta and assorted devs are just ignoring as a problem) is that it's easy to actually make VR nausea much worse and last longer by attempting to power through it; the only reliable way to get over it is lots of light exposure with very regular breaks (in other words, the good ol' Virtual Boy safety setting). I think that's a big part of why Apple is doing their best to pretend that any VR experiences that also involve moving your viewpoint around don't exist. Static or 'grab and drag the world around' styles work much better for avoiding nausea in general.
