LightSpace Technologies have developed multifocal technology to overcome the visualization problem and reconstruct visual 3D content
with both vergence and accommodation depth cues across whole observable field of depth: “AR Displays: Next-Generation Technologies to Solve the Vergence–Accommodation Conflict”.
There are recent research that have focused on various undesired aspects of single focal plane stereoscopic 3D including “connecting dots” test and cognitive capabilities analysis that show serious (up to 40%) 3D image recognition slow down if using such a systems. Some of the relevant research have been listed below:

VAC is one of the leading reasons current single and fixed focal plane headsets cannot be well used for under 10m range 3D visualizations.
