Abstract
The development of metaverse has the potential to revolutionize people's life. As the entry to metaverse, virtual reality (VR) and augmented reality (AR) technologies are gaining ever‐increasing attention. However, there is vergence‐accommodation conflict problem for most VR or AR 3D displays. In this paper, we propose to realize vari‐focal near‐eye displays based on tunable geometry phase liquid crystal lenses to address this problem. Experimental results validate that images can be rendered at different depth as the tunable lenses change their focal lengths. Thus, correct accommodation cue can be induced, and 3D visual fatigue could be significantly suppressed.
