This article analyzes the four core aspects of polarization optical system design and presents practical principles for optical layout based on engineering experience, helping engineers avoid common pitfalls in polarization design.

Retinal eye-tracking technology offers significant advantages in terms of accuracy, power consumption, and size—requiring only a one-time calibration for lifelong use without being affected by device displacement—yet the collection and storage of retinal data also raise new privacy concerns.

This analysis examines the physical principles and engineering bottlenecks of the three mainstream AR optical waveguide technologies—Surface Relief Gratings (SRG), geometric arrays, and Volume Holographic Gratings (VHG)—and highlights how new materials like silicon carbide (SiC) are delivering a disruptive, game-changing advantage; the ultimate winner will be the first company to successfully balance the "trilemma" of high performance, low cost, and mass producibility.

California's proposed SB 1130 bill seeks to prohibit the use of wearable devices, such as smart glasses, to record audio or video in commercial settings without consent; it would also mandate that such devices be equipped with a recording indicator that cannot be disabled, with violations punishable by fines or imprisonment.

A deep dive into the "optical ledger"—covering factors such as optical engine volume, waveguide constraints, and visual perception—to analyze the vast differences in weight and price between RayNeo’s full-color spatial computing glasses and their monochrome green information glasses.

A new generation of AI cooking glasses is on the horizon; by addressing mass-production challenges through practical optimizations—such as a swappable battery design and a monochrome display—and integrating the "God of Cookery" (Shishen) large model alongside embodied AI technology, these glasses mark the official entry of AI eyewear into the high-frequency vertical scenario of the home kitchen.
