我们的眼睛会随着年龄而变化———这是事实。但是我们可以做很多事情来减缓这个过程并保护我们的眼睛。

我们的眼睛在生命的头两年发育得最快，在青少年时期又会快速生长。到了二十岁，眼睛完全发育成熟，而大多数人就知道自己用不用戴眼镜了。

从四十岁左右开始，许多人发现很难看清近处的东西。这是因为他们患了老花眼。没什么好担心的，如果他们戴上合适的眼镜，问题便迎刃而解。但是，有些人会患上严重的眼疾。

随着年龄的增长，在弱光下很难看清东西，所以要更多光线。但强光对我们的眼睛有害，我们会发现有些颜色很难分辨。当我们变老时，我们的眼睛会变得干涩。我们可以做下面几件事情来减缓这个过程。

不要抽烟。许多研究表明吸烟对我们的眼睛有害。吸烟的人更容易得眼疾。戒烟是我们能做的保护眼睛的最佳方法之一。

做检查。视力测试不仅仅是检查你的视力，它还可以显示眼部疾病的早期迹象，也可以发现其他健康问题。

离开屏幕休息一下。屏幕会发出大量蓝光，会使我们的眼睛干涩又疲劳。每看20 分钟屏幕就试着休息20 秒钟，注视20 英尺外的事物。

此外，做运动对我们的全身和眼睛都有好处。多吃水果和蔬菜也有助于保护我们的眼睛。
