Core Viewpoint - The increasing prevalence of myopia among adolescents has become a global public health challenge, necessitating long-term prevention strategies integrated into daily life, including lifestyle habits, eye behavior, and regular check-ups [1] Group 1: Myopia Prevention Strategies - Myopia prevention must shift focus to preschool children under 6 years old due to insufficient hyperopia reserves in school-age children [2] - Children can be categorized based on their hyperopia reserves into three groups for differentiated management: sufficient, relatively insufficient, and pre-myopic [2] Group 2: Recommendations for Different Categories - For children with sufficient hyperopia reserves (not lower than recommended values), measures include encouraging outdoor activities, cultivating good eye habits, and optimizing visual environments, with follow-up monitoring every 6-12 months [4] - For children with relatively insufficient hyperopia reserves (greater than 0.75D but below recommended values), stronger interventions are advised, such as increasing outdoor activities and reducing near work, with follow-up every 3-6 months [5] - For pre-myopic children with low hyperopia reserves, intervention effects may be limited, but low-concentration atropine treatment is recommended for those below +1.00D, and combined optical methods for those with a family history of myopia [6][7] Group 3: Daily Prevention Practices - Adopting scientific eye care methods and maintaining them over time is more effective than temporary measures, with the "20-20-20" rule being a practical approach [9] - Daily outdoor activity of over 2 hours is essential for healthy eye development, and regular vision checks every 6 months are recommended for myopic adolescents [9] - A diet rich in dark fruits and vegetables, which contain carotenoids, can help protect the eyes, while limiting sugar intake is crucial as higher consumption correlates with increased myopia rates [9] Group 4: Long-term Commitment to Eye Health - Myopia prevention requires a comprehensive understanding of its causes, proper lens fitting, consistent eye care, healthy eating, and regular monitoring, all contributing to a protective network for children's vision [10]

Core Viewpoint - The article emphasizes the increasing risk of poor spinal health among children during the winter vacation due to unhealthy habits associated with leisure activities, particularly the use of electronic devices and improper sitting postures [1][2]. Group 1: Health Risks - Prolonged use of mobile phones can lead to significant pressure on the cervical spine, potentially resulting in "text neck" [1] - Poor sitting posture while gaming may cause the normal curvature of the lumbar spine to disappear, leading to "gaming back" [1] - Other harmful postures, such as watching TV for extended periods or lying sideways while binge-watching, can contribute to spinal issues [1] - These unhealthy habits can increase the risk of scoliosis and myopia, along with causing frequent neck and shoulder pain, and poor posture [1] Group 2: Prevention and Improvement Methods - The "20-20-20 rule" is recommended, which suggests looking at an object 20 feet away for 20 seconds after every 20 minutes of screen time [2] - Proper sitting posture should follow the three right angles rule: eyes level with the screen, elbows at 90 degrees, and knees at 90 degrees with feet flat on the ground [2] - Parents are advised to monitor for warning signs of scoliosis, such as frequent shoulder pain or uneven shoe wear, and to encourage regular physical activity and check-ups to maintain spinal health [2]

Core Viewpoint - The discussion around "pseudo-myopia" has gained attention, highlighting its reversible nature and the importance of timely intervention to prevent it from developing into true myopia [1][30]. Group 1: Understanding Pseudo-Myopia - Pseudo-myopia, also known as "accommodative myopia," occurs when the ciliary muscles in the eye become overworked due to prolonged near vision tasks, leading to temporary blurred vision at distance [9][11]. - This condition is a warning signal from the body indicating excessive eye strain, which can be reversed with proper care [5][7]. Group 2: Self-Assessment Methods - Two simple self-assessment methods can help determine if blurred vision is due to pseudo-myopia: resting the eyes and observing improvement, or undergoing a cycloplegic refraction test at a hospital [12][15]. Group 3: Causes of Pseudo-Myopia - Common causes include prolonged near work, poor lighting conditions, and continuous focus without breaks, which can lead to muscle fatigue and temporary loss of vision clarity [17][18][20]. Group 4: Reversal Strategies - The "20-20-20 rule" suggests taking a 20-second break to look at something 20 feet away every 20 minutes to relieve eye strain [22]. - Exposure to natural light and engaging in outdoor activities can help stimulate the retina and prevent eye axis elongation [23]. - Performing eye exercises and ensuring adequate sleep are also recommended to maintain eye health [25][26]. Group 5: Common Misconceptions - Misunderstandings about pseudo-myopia include the belief that it is harmless and will resolve on its own, which can lead to missed opportunities for early intervention [28].
