Core Viewpoint - The increasing prevalence of myopia among children and adolescents in China has raised concerns about eye health, leading to a market for "anti-myopia" school supplies, particularly exercise books, which may not meet safety standards [1][4][10] Group 1: Industry Standards and Regulations - The national mandatory standard "Hygienic Requirements for Anti-Myopia Learning Supplies for Children and Adolescents" (GB40070-2021) was implemented on March 1, 2022, setting specific requirements for exercise books, including D65 brightness between 55.0% and 85.0%, D65 fluorescence brightness ≤ 5.0%, and a basis weight of ≥ 65.0 g/m² [4][10] - The recommended standard "Exercise Books" (QB/T1437-2023) aligns with the mandatory standard in terms of D65 brightness and fluorescence brightness requirements, but it is not as strictly enforced [13][10] - The market has seen confusion regarding the term "new national standard," as the mandatory standard must be adhered to for all relevant products, and any non-compliance renders the product unfit for sale [10][13] Group 2: Product Quality and Consumer Awareness - A media investigation revealed that about 30% of the tested exercise books labeled as "anti-myopia" did not meet national standards, with some showing excessive fluorescence brightness [1][10] - Parents often rely on visual cues, such as the color of the paper, to select products they believe are safer for their children's eyes, but there is skepticism about the actual effectiveness of these products [1][7] - Experts emphasize that while yellowish paper may reduce glare, overly yellow paper can be counterproductive, and the presence of fluorescent agents in paper can negatively impact eye health [7][8][10] Group 3: Recommendations for Eye Health - Medical professionals suggest that relying solely on "anti-myopia" exercise books is not scientifically supported, and recommend a combination of outdoor activities, proper lighting, and good reading posture to protect eye health [17]
