The video explains the science behind nearsightedness. When we use our eyes for prolonged periods to look at screens or books, it puts strain on the lens, causing changes in its shape. This can lead to nearsightedness. To protect our vision, we should take regular breaks, rest and relax our eyes, and eat foods that are good for eye health. Taking care of our eyes means taking care of our world. 大家好,你知道你的眼睛为什么会近视吗? 今天我们就来揭秘近视背后的科学原理 当你在看手机电脑或者书本的时候 你的眼睛其实在经历一场马拉松 因为眼睛里有一个像相机一样的晶状体 它需要不断地调整焦距 来保证我们看到的东西越来越清晰 但是,长时间近距离使用眼睛会让镜头超负荷工作 导致眼睛的形状发生改变 如果我们的眼睛是一支足球队 长时间的近距离使用会让它不停地进攻 却忘了防守 结果就是球门大开,防守全线崩溃 所以,为了保护我们的视力队 我们还要定期让眼睛休息、蜿蜒、放松 还要吃一些有益于眼健康的食物哦 记住,保护好你的眼睛就是保护好你的世界 不要忘了点赞关注哦 下期再见
