Unless there’s some radio wave danger, I don’t see how headsets could be harmful. Your eyes are not actually focusing on a close screen, they’re focused however far away the objects appear to be. Is there a danger to letting your eyes be unfocused and placing an iPhone right next to them (letting the screen be blurry, not trying to focus on it). Maybe it’s the inner ear that is going to get hurt after prolonged disorientation, but astronauts should surely have that worse and I haven’t heard of any studies about it. Maybe something will show up about it. I don’t see an obvious mechanism where this is harmful and VR headsets have been around long enough that this should be a well-understood safety space.
