I dunno. Glasses moving around, even getting a new prescription adjusts your view and distortion. Pushing them up slightly to scratch or wipe something away from your eyes. Putting on on-top sunglasses or ballistic eye protection.

My theory was always that constant exposure to 3D games with their wild cameras, along with glasses causing everything you see to be optically jostle-able, trains people to not get woozy when VR does weird things.

I've got friends who can't play even normal 3D games because the camera moving made them nauseous eventually. And that's on a screen far from their faces. None of my "gamer" friends have had problems. 

Backing this up, there's articles and forum posts from when HL2 came out complaining that the fast vehicle sequences gave them nausea. 

I guess that's not the right line of reasoning, though.
