开学季，不能把孩子的这笔“存款”透支了！

font-weight: bold;">开学后近距离用眼增多、日间户外活动减少，若不及时干预，可能增加近视发生风险。</span></section><section></section><section>国家卫生健康委办公厅印发的《近视防治指南（2024年版）》这样定义远视储备：新生儿眼球一般为远视眼，屈光度约为+2.50～+3.00D，这种生理性远视称为远视储备，随着生长发育逐渐降低。</section><section></section><section>河南省儿童医院眼科主任卢跃兵表示，通俗地说，这是孩子与生俱来的“视力存款”，随着眼球发育，这笔“存款”会逐渐消耗。透支远视储备的常见原因有以下几种：</section><section></section><section><span style="color: #7b0c00; font-weight: bold;">首先，近距离用眼过度</span>，除了使用电子产品，长时间写作业、练字、绘画、搭积木、阅读绘本等同样属于高强度近距离用眼，不少家长严格限制孩子玩手机，却默许孩子连续伏案三四个小时刷题、搭积木，睫状肌持续痉挛，可能刺激眼轴过快拉长。</section><section></section><section><span style="color: #7b0c00; font-weight: bold;">其次，日间户外活动不足</span>，研究表明增加日间户外活动可降低儿童近视发生风险。有研究提示，睡眠不足也可能与儿童近视风险增加有关，眼睛得不到充分休息，视疲劳会持续累积，加快近视进展。</section><section></section><section><span style="color: #7b0c00; font-weight: bold;">此外，读写和照明环境不规范也是一大原因</span>，如只开台灯不开房间主灯、趴着躺着看书、在昏暗环境下写作业等。</section><section></section><section style="text-align: center;"><img class="rich_pages wxw-img js_insertlocalimg" style="width: 100%;" src="https://qnym.aiwulongrencai.com/20260913/17892825661442234003.jpeg" /></section><section><span style="font-size: 14px;
