我們的眼睛會(huì)隨著年齡而變化———這是事實(shí)。但是我們可以做很多事情來減緩這個(gè)過程并保護(hù)我們的眼睛。

我們的眼睛在生命的頭兩年發(fā)育得最快，在青少年時(shí)期又會(huì)快速生長。到了二十歲，眼睛完全發(fā)育成熟，而大多數(shù)人就知道自己用不用戴眼鏡了。

從四十歲左右開始，許多人發(fā)現(xiàn)很難看清近處的東西。這是因?yàn)樗麄兓剂死匣ㄑ邸]什么好擔(dān)心的，如果他們戴上合適的眼鏡，問題便迎刃而解。但是，有些人會(huì)患上嚴(yán)重的眼疾。

隨著年齡的增長，在弱光下很難看清東西，所以要更多光線。但強(qiáng)光對(duì)我們的眼睛有害，我們會(huì)發(fā)現(xiàn)有些顏色很難分辨。當(dāng)我們變老時(shí)，我們的眼睛會(huì)變得干澀。我們可以做下面幾件事情來減緩這個(gè)過程。

不要抽煙。許多研究表明吸煙對(duì)我們的眼睛有害。吸煙的人更容易得眼疾。戒煙是我們能做的保護(hù)眼睛的最佳方法之一。

做檢查。視力測(cè)試不僅僅是檢查你的視力，它還可以顯示眼部疾病的早期跡象，也可以發(fā)現(xiàn)其他健康問題。

離開屏幕休息一下。屏幕會(huì)發(fā)出大量藍(lán)光，會(huì)使我們的眼睛干澀又疲勞。每看20 分鐘屏幕就試著休息20 秒鐘，注視20 英尺外的事物。

此外，做運(yùn)動(dòng)對(duì)我們的全身和眼睛都有好處。多吃水果和蔬菜也有助于保護(hù)我們的眼睛。
