Emerging virtual and augmented reality (VR/AR) systems can produce highly immersive experiences, but also induce visual discomfort, eyestrain, and nausea for some users. One of the sources of these symptoms is the lack of natural focus cues in all current VR/AR near-eye displays. These displays project stereoscopic image pairs, driving the vergence state of the eyes to arbitrary distances. However, the accommodation, or focus state of the eyes, is optically driven to a fixed distance. In this work, we empirically evalaute monovision: a simple, yet unconventional method for potentially driving the accommodation state of the eyes to two distances by allowing each eye to drive focus to a different distance.
