Oculus Research to Present Focal Surface Display Discovery at SIGGRAPH
VR sickness is primarily caused by latency.  ie you move your head, the image takes a few milliseconds to respond and you feel dizzy.  But there are other types of VR sickness, like the inability to focus on an object.  This research improves your ability to focus on objects at different depths.  Your vision is less blurry.  So yes, this research does help eliminate nausea in VR.  To say otherwise is misleading.
