Achromatic Metalens‐Enabled Mixed Reality Near‐Eye Display for Adaptive Visual Enhancement in Complex Environments

Abstract Traditional optical imaging systems are limited by their narrow spectrum response, and static interaction modes, which can't meet visual enhancement requirements in complex environments such as low‐light conditions, and underwater scenarios. Here, the world's first amphibious achromatic metalens (AML)‐enabled mixed reality near‐eye display (NED) system is demonstrated to redefine human‐environment interaction. The AML with a diameter of 5 mm, focal length of 3 mm is designed using artificial intelligence to achieve broadband chromatic aberration reduction (450–850 nm) with full width at half maximum 445–620 nm. The AML addresses the color difference limitation of conventional optical systems and achieves high‐resolution imaging across the visible to near‐infrared. An amphibious mixed reality NED prototype is then developed by incorporating the AML into a lightweight, waterproof camera. The prototype supports real‐time depth of field prediction with millisecond‐level latency. At daytime, the camera's color reproduction closely matches that of commercial cameras, while at nighttime, it produces clear images with near‐infrared fill light. The prototype's performance in underwater and low‐light environments demonstrates its potential to enhance human vision's interaction with nature. This work provides an extensible platform for the next generation of visual enhancement technology, fostering the deep integration of wearable optics and computational imaging.
