I understand that this is still a big problem in the air force when training fighter pilots with VR headsets. The fixed focal length means extended use still leaves pilots disoriented even after taking the headsets off. I would imagine this will hamper real world adoption and keep VR pretty niche for the time being. Using light-fields is the obvious solution but that's still a pretty nascent tech. It's not entirely clear what problem VR is trying to solve in a lot of situations where's it's claimed to apply (like office use). There's obviously some places where it could be quite useful, but light-field fixed screens might offer a lot of similar benefits for a lot of these applications and at this point at least, that tech is a bit further along (and might be more comfortable for users).
