回到家的时候已经六点钟了，妈妈喊他赶紧吃饭，但小月吃饭的时候，他心里还老是想着《十万个为什么》那本书里的内容，小月还把《十万个为什么》拿到饭桌上看，他边看书边吃饭，吃得非常不专心，这样对肠胃很不好的。
到了晚上的时候，小月已经洗漱完毕，爬上床睡觉了。但他翻来覆去总是睡不着，心里挂念他的书没看完，想看书的心痒痒的，他连忙下床把《十万个为什么》拿到床上躺着看，看到眼睛很累睁不开了，才依依不舍把书拿开来睡觉。
几个月过去了，小月发现他看东西模模糊糊的，不像以前那样清晰。小月赶快去医院检测视力。医生告诉小月：他已经轻度近视了，由于用眼不当，不好好爱护眼睛。经常在灯光暗弱的地方看书造成的。并劝告他以后要爱护眼睛，保护视力很重要。小月非常后悔，但事情已经造成了，只好以后注意。小月现在已经知道要好好保护眼睛了，他现在看书的时候都专心致志，再也没同时干别的事情了。

眼睛是心灵的窗户。只要眼睛有神，有魂。这样心就会光明澄清、独具魅力。
我的视力在我们的班中一直是不错的。以前三年级、四年级我在体检时的视力度数一直是5.0、5.1，而今天体检的视力却令我大吃一惊。
今天上午，我们学校统一要进行一次体检。到了第三节课，老师和我们说要带我们去体检。
一进房间，我就迫不及待地跑到检查视力的地方，自信的准备接受检查。然而，当开始测试的时候，我才发现我的左右眼模模糊糊，视力表的下面什么都看不到，只知道有一大片字母。检查结果——左眼4。8度，右眼4。9度。
我很吃惊，也很有感触。问了问同学们的视力，结果大部分同学的视力竟然比我还差！仅仅有两三位同学视力在5。0以上！
事后，我想了许多……平日躺着看书，书写姿势不正确，看起来是小事，但是它们也会“积少成多”啊！
现在明白了，只有长期保护眼睛，爱护眼睛，养成良好的看书姿势，才能不使自己的视力下降！切记：保护视力已迫在眉睫！
