The Nreal Light is a lightweight phone-powered augmented reality glasses device developed by Nreal (now rebranded as Xreal), unveiled at CES in January 2019 and released commercially in 2020 (Korea) and December 2021 (United States) at a price of approximately $599. The Nreal Light was among the first consumer-accessible AR glasses to offer 6 degrees of freedom (6DoF) spatial tracking in a sunglasses-like form factor weighing just 88 grams. Unlike display-only smart glasses, the Nreal Light featured dual 1080p Sony micro-OLED displays, SLAM-based spatial mapping through dual tracking cameras, and the ability to anchor virtual objects in physical space—capabilities previously found only in enterprise devices like Microsoft HoloLens. By tethering to a compatible smartphone via USB-C, the Light delivered mixed reality experiences at a fraction of the cost of standalone AR headsets.
