    With the concept of metaverse gradually becoming popular, wearable near-eye display devices for virtual and augmented reality (VR/AR) have received considerable attention. An ideal VR/AR headset device must integrate the display, sensor, and processor into a compact form factor, so that people can wear it comfortably for long durations, while providing a good immersive experience and friendly human-computer interaction experience. The design concept of visual comfort is crucial for the next generation VR/AR equipment. Among many display technologies that can provide three-dimensional visual effects, holographic display technology can provide real and natural three-dimensional display effects including all three-dimensional viewing clues. Meanwhile, owing to its diffraction imaging characteristics, holographic display technology has unique advantages in human visual aberration correction and maintaining compact overall dimensions, and it has become a potential ideal technical solution for near-eye display equipment. In this review, the latest developments in the holographic near-eye display technology was investigated and summarized from the perspective of visual comfort. First, the human visual system was introduced in the context of visual perception. Then, the research works of holographic near-eye display in eyebox, field of view, speckle noise, hologram generation algorithms, and full-color display were comprehensively reviewed. Finally, the potential application scenarios of holographic near-eye display technology were summarized and discussed in this study.
