Emerging virtual and augmented reality (VR/VR) displays must overcome the prevalent issue of visual discomfort to provide comfortable user experiences. In particular, the mismatch between vergence and accommodation cues inherent to most stereoscopic displays has been a long‐standing challenge. We evaluate several display modes that have the promise to mitigate visual discomfort caused by the vergence‐accommodation conflict (VAC), and improve user comfort as well as performance in VR/AR applications. In particular, we explore light field, focus‐tunable, and monovision display modes. Whereas light field displays seek to synthesize the 4D light field over the eye box of the viewer, for example with a stacked liquid crystal display architecture, focus‐tunable display mode use either programmable liquid lenses or actuated displays to adaptively place the accommodation plane at different distances during the VR/AR experience. Monovision is an unconventional mode that accommodates each eye of the observer at different depths, a technique commonly used in ophthalmology. We evaluate the effectiveness of several different display modes enabled by light field and focus‐tunable near eye displays.
