There's no released VR system that has more than one focal depth, so I'm not sure what you're talking about, here. Whether you're looking at something near or far away in VR, your eyes don't change accommodation (focus), but they may change vergence (difference in direction between eyes). So everything is always in focus. It's easy enough to observe - look at a near object in VR and then, without moving your eyes, concentrate on a far object and note that you can still see the detail clearly.
