The eye has a variety of depth cues as listed in Wikipedia: Depth_perception. Currently, most VR headsets and 3D displays can simulate the binocular vergence depth cue by showing different images to the left and right eyes. This forces the eye to rotate inwards to perceive near objects. Similar to cameras, the human eye has..."
