<h3> 一场新冠肺炎疫情的突袭，全国约2亿儿童青年少面临延期开学，网课成了延期开学期间孩子们学习的必修课。</h3> <h3> 如何在长时间、大规模的“宅家学习”行动中落实近视防控指导，保护儿童青少年眼健康，科学推进“停课不停学”，成为一项艰巨挑战。
</h3> <h3> 针对“停课不停学”期间学生电子产品的使用，全国综合防控儿童青少年近视专家充分发挥专业，提出了一系列有指导价值的防控措施。</h3> <h3> 小学阶段的学生们建议每天线上学习的时间应控制在2.5～3小时以内。</h3><h3> 中学阶段的学生们建议每天线上学习的时间应控制在4～5小时以内。<br></h3> <h3>小学阶段的孩子，每节课20分钟为宜。</h3><h3>中学阶段的孩子，每节课30分钟为宜。</h3> <h3> 充足睡眠是眼部健康的基础。建议小学生每天睡眠时间达到10小时，初中生9小时。<br></h3> <h3> 网上学习的同时，我们每天都要花大量时间用于近距离的阅读和书写，所以读写习惯对预防近视也尤为重要。</h3><h3> 读书写字，也要做到“一拳一尺一寸”，即眼睛离书本一尺，胸口离桌沿一拳，握笔的手指离笔尖一寸。<br></h3> <p style="max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 14px; letter-spacing: 1.5px; text-align: justify; white-space: normal; overflow-wrap: break-word !important;"><span style="max-width: 100%; font-size: 16px; overflow-wrap: break-word !important;"> 最后向您推荐一套</span></h3><p style="max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 14px; letter-spacing: 1.5px; text-align: justify; white-space: normal; overflow-wrap: break-word !important;"><span style="max-width: 100%; font-size: 16px; overflow-wrap: break-word !important;"> 由我国飞行员视力标准的制定者研究推出的</span><span style="font-size: 16px;">有</span><span style="font-size: 16px;">助于恢复视力的“米字操”。</span></h3><p style="max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 14px; letter-spacing: 1.5px; text-align: justify; white-space: normal; overflow-wrap: break-word !important;"><span style="max-width: 100%; font-size: 16px; overflow-wrap: break-word !important;"> （适用于近视500度以下的患者）</span></h3><p style="max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 14px; letter-spacing: 1.5px; text-align: justify; white-space: normal; overflow-wrap: break-word !important;"><span style="max-width: 100%; font-size: 16px; overflow-wrap: break-word !important;"> ①看手指前后移动3次；</span></h3><p style="max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 14px; letter-spacing: 1.5px; text-align: justify; white-space: normal; overflow-wrap: break-word !important;"><span style="max-width: 100%; font-size: 16px; overflow-wrap: break-word !important;"> ②向上下各看3次；</span></h3><p style="max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 14px; letter-spacing: 1.5px; text-align: justify; white-space: normal; overflow-wrap: break-word !important;"><span style="max-width: 100%; font-size: 16px; overflow-wrap: break-word !important;"> ③向左、右、上、下各看3次；</span></h3> <h3> ④眯眼睛3次；<br></h3> <h3> ⑤顺时针、逆时针各3圈<br></h3> <h3> 疫情特殊时期，我们要学会合理用眼，远离近视，共同努力渡过难关。<br></h3>
