But if I understand correctly the optics can't recreate how our eyes focus on near and far things in reality. So if something is supposed to be 100 meters away it will still be physically like focusing on something 1-2 meters away due to how the optics work. That's the whole VAC issue mentioned in the article.

That's true. They still can't without eye tracking and physically moving lenses. I've seen a prototype in the news that could do that. But of course it's mechanically highly complex. Perhaps liquid/gel lenses could do the same job (similar to how our eyes work).

I've never heard of this actually causing harm though, except some questions were raised about kids whose eyes are still developing. It would be similar to looking through a microscope or binoculars for hours, which is not unheard of in human history (e.g. researchers, lookouts on ships)
