Core Viewpoint - The article emphasizes the increasing prevalence of myopia among children and adolescents in China, highlighting the need for awareness and preventive measures to combat this public health issue [2][3][4]. Group 1: Myopia Statistics and Trends - As of 2022, the overall myopia rate among children and adolescents in China is 51.9%, with specific rates of 36.7% in elementary school, 71.4% in middle school, and 81.2% in high school [2]. - The myopia rate for first-grade students is approximately 10%, which escalates to nearly 60% by sixth grade, indicating an average increase of about 9 percentage points per grade [2]. Group 2: Contributing Factors - Environmental factors, such as academic pressure and increased screen time, are significant contributors to the rise in myopia among children [3]. - Insufficient outdoor activity is also a critical factor, as lack of exposure to natural light can increase the risk of developing myopia [3]. Group 3: Preventive Measures - Experts recommend developing good eye habits, engaging in outdoor activities, and maintaining a healthy diet to mitigate myopia risks [3]. - The "20-20-20" rule is suggested as an effective method for eye relaxation, which involves looking at an object 20 feet away for 20 seconds after every 20 minutes of close-up work [3]. Group 4: Vision Check Recommendations - Regular vision checks are advised, with specific frequencies based on the child's risk level: once a year for low-risk children, every six months for those with mild myopia, and every 3-4 months for those with moderate to high myopia [4]. - Establishing a refractive development record for children is recommended to monitor vision changes and enable early intervention [4]. Group 5: Collaborative Efforts - The Henan Provincial Eye Hospital is collaborating with local education departments to create refractive health records for students and provide on-site guidance on eye health [4]. - A big data platform for myopia prevention is being developed to identify high-risk students early and promote healthy behaviors [4]. Group 6: Treatment Options - The article discusses the use of OK lenses (orthokeratology lenses) for myopia control, which reshape the cornea overnight to improve daytime vision [6]. - Caution is advised for certain children regarding the use of OK lenses, particularly those with active eye conditions or poor hygiene practices [6][7].
