Core Viewpoint - The increasing prevalence of myopia among children has led to a surge in demand for lutein products, with many parents believing these products can prevent myopia, despite insufficient clinical evidence supporting such claims [1][2][26]. Group 1: Market Trends and Consumer Behavior - The market for children's lutein products is expanding, with many parents purchasing these products under the misconception that they can prevent myopia [1][22]. - Many lutein products on the market are gummy forms, which may contain sugars and other additives, raising concerns about their health implications for children [22][24]. - The overall myopia rate among Chinese children and adolescents is reported to be 51.9%, prompting parents to seek preventive measures [6]. Group 2: Misleading Marketing Practices - Some companies are using misleading marketing tactics, suggesting that lutein can prevent or control myopia, despite a lack of scientific evidence [2][26]. - Products like "Brieyeye" and "NaturElan" have been found to make claims about myopia prevention that are not substantiated by clinical evidence, often using expert endorsements to lend credibility [3][4][11][12]. - The use of patents in marketing claims is often misleading, as many patents cited do not relate to myopia prevention but rather to other health benefits [16][17][21].
