眼屎究竟是什么?

What are Eye Boogers?

眼屎 (以及它其他的叫法)
Sleep, eye crusties, eye boogers, eye dust,
睡觉醒来时眼角上的东西
eye gunk, the stuff in the corner of your
也就是我们常说的眼屎
eyes when you wake up, also known as eye schnooters…
那是什么
What is that?
眼屎是蛋白质 油
Eye crusties are a mixture of protein, oils,
死皮细胞和细菌混合而成的
dead skin cells, and even bacteria.
从化学的角度来说它是三层复杂混合物质
Chemically speaking, it’s a three-layercomplex mixture of stuff.
眼屎最里面的那一层是粘蛋白类蛋白质
The innermost layer is made of proteins called mucins,
这种蛋白质有一层糖衣
which have a coat of sugars that helps
用它来帮助自己吸收水分来形成一层粘液保护层
them trap water and form a nice protective layer of gooey mucus.
第二层实际上就是
The next layer is actually…
你的眼泪 眼泪包涵了各种物质
your tears, which contain a variety of substances, but
但其实它们主要都是盐水
really they’re mostly salt water.
最外层是一种复杂的油性混合物叫作油脂
And the outermost layer is a complex oily mixture called meibum,
它可以锁水保湿
which helps seal that
让你的眼睛不会变的干涩
moisture in and protect your eyes from dryingout.
眼屎是由很多东西组成的
It’s made of a bunch of things,
你只看见了它的一小部分
just a few of which you’re seeing here.
它的第三层是蛋白质 水和油
This three-layer film of protein, water,
它们可以避免其他物质的进入
and oily stuff helps protect your eyes from the
让你白天看的更清楚
elements and keeps you seein’ good. Normally,
白天的时候
during the day,
你通过眨眼来排出眼睛中的杂质
you blink excess eye stuff out of the way.
但是到了晚上 你明显 没办法眨眼
But at night, you’re obviously…not blinking.
因此在眼角形成了干的眼屎
So it builds up and dries out instead, and collects at the corners.
白天由于体温一些脂肪在油脂中融化
Some of the fats in meibum melt just under daytime human body temperature.
睡觉时 体温会下降到
When we sleep, our body temperature can drop a little
油脂的融点以下
below this melting point, encouraging
这导致这些油脂凝固形成眼屎的外壳
those fats to solidify a little more, which enhances that eye crusty crustiness.
你的眼屎是硬是软取决于
How crusty or soft your eye gunk is depends
你眼睛的干涩情况
on how dry your eyes are.
眼睛越干涩 外壳越硬
The drier your eyes, the crustier the crusties.
大多数时候 没必要担心眼屎
Most of the time, eye crusties are nothingto worry about.
但是过多地眼屎会造成眼病 比如结膜炎
But excess gunk can be a symptom of eye disease, like conjunctivitis.
大多数时候很多人
For most of us, most of the time,
都保持着清醒的状态
it’s just part of waking up.
