R/AR optical lenses are core optical components in Virtual Reality (VR) and Augmented Reality (AR) devices, primarily serving to display virtual images, blend virtual content with the real environment, and facilitate visual interaction with the human eye. Through the use of precision lenses, optical modules, display panels, and optical path designs, these systems magnify, collimate, and optimize images output by micro-displays, providing users with a high-definition, highly immersive visual experience.Driven by advancements in the metaverse, spatial computing, wearable technology, and human-computer interaction, VR/AR optical lenses are widely used in fields such as VR headsets, AR smart glasses, industrial assistive devices, medical training, education, gaming, and smart manufacturing. Their performance directly impacts key device attributes, including the field of view (FOV), image clarity, weight, wearing comfort, and overall user experience.VR/AR optical lenses primarily fall into…
