As digital life and outdoor activities continue to increase, the demand for eyewear lenses has become more diverse in modern society. For users who spend long hours on electronic devices, blue light radiation has become a potential threat to eye health. In addition, exposure to ultraviolet (UV) rays and intense light in outdoor environments can also lead to eye discomfort and fatigue. To address these challenges, lenses combining photochromic and blue light filtering technologies have emerged as an innovative solution in the eyewear industry. These lenses not only automatically adjust their tint based on changes in light conditions but also effectively filter blue light, providing users with comprehensive eye protection.
