The History of Smart Glasses - At a Glance

　　The development of smart glasses has evolved from technical prototype exploration to AI large-model empowerment, advancing from B-end trials to consumer-level popularity. Centered on breakthroughs in display, chip and AI technologies, alongside scenario expansion and ecological improvement, the industry entered an explosive phase of "AI + lightweight + independent terminals" starting in 2023.

　　I. Early Exploration: Technological Groundwork & Concept Validation (1960s - 2011)

　　This era focused on verifying the feasibility of wearable display and computing. In 1968, Ivan Sutherland created the "Sword of Damocles" – the first head-mounted display to overlay virtual information on real vision, laying the foundation for AR technology. In the 1980s, Steve Mann from the University of Toronto developed the i-Tap prototype and later EyeTab, achieving miniaturization and network connectivity, earning him the title "Father of Wearable Computing." Commercial attempts emerged in the 2000s: Vuzix launched the first commercial display smart glasses in 2003, Philips released camera-equipped Wi-Fi glasses in 2004-2005, and Intel, Microsoft explored auxiliary computing functions through projects like Project Skylight.

　　II. Commercial Trials: Highs & Setbacks (2012 - 2022)

　　2012 marked a turning point with Google Glass – integrating a camera, voice control and transparent display, it was named a Time "Best Invention" but failed in the consumer market due to its $1,500 price tag, privacy concerns and vague scenarios, shifting to B-end use in 2015. Microsoft’s 2016 HoloLens established a benchmark for professional AR glasses, leveraging spatial computing in industries and healthcare. The 2017-2022 period saw technological maturation: waveguide, cloud-edge AI and SLAM algorithms improved, while devices became lighter. Huawei, Xiaomi launched smart audio glasses, and Meta (then Facebook) laid out AR/VR technologies. The 2021 Ray-Ban Stories, a collaboration between Meta and EssilorLuxottica, pioneered the "fashion + intelligence" route focusing on photography and social interaction.

　　III. AI-Driven Boom: Consumer Adoption & Independent Terminals (2023 - Present)

　　On-device AI large-model deployment fueled the 2023 industry boom. Ray-Ban Meta (upgraded from Stories) became a phenomenon, with 2.24 million 2024 sales accounting for 60% of the global market; domestic brands like Rayneo and Rokid accelerated iterations. From 2024 to early 2026, key advancements included mass-produced Qualcomm Snapdragon AR1 chips, 6,000-nit binocular full-color Micro OLED screens, and eSIM-enabled independence (e.g., Rayneo X3 Pro). Products differentiated into $299 AI camera glasses and $799 AI+AR display glasses. Vertical scenarios expanded with education (Nano Box AI Learning Glasses) and translation (Liang Liang Vision Leion Hey2) glasses; Meta plans to double Ray-Ban AI glasses production to 20 million units, while domestic brands secured over 1 billion yuan in financing and policy subsidies.

　　IV. Core Evolution Logic & Key Turning Points

　　Smart glasses evolved by solving core pain points: from verifying basic functions to consumer and B-end exploration, finally entering AI-driven iteration. Key turning points include Google Glass pioneering consumer smart glasses, HoloLens validating professional scenario value, Ray-Ban Stories merging fashion with intelligence, and large-model on-device deployment + eSIM enabling independent terminal transformation. Each breakthrough addressed bulkiness, high costs and single-function limitations, pushing the industry from niche to mainstream.

　　V. Future Trends

　　The industry will move toward independent terminalization (eSIM and native apps reducing phone reliance), lightweight fashion (30g+ designs with refractive lens compatibility), deep AI integration (multimodal interaction and customized vertical models), and open ecosystems (Google Android XR and Meta’s ecosystem fostering third-party cooperation).
