A Clear Picture of Contact Lenses 「看清」隐形眼镜

课文朗读

课文讲解

繁體中文譯本

Many people around the world suffer from myopia, more commonly known as nearsightedness, and Taiwan may have the world’s highest rate of affliction. As a result, you might expect most people in Taiwan to wear glasses, but this isn’t the case. Lots of people rely instead on a convenient alternative, contact lenses.

世界上有许多人受屈光不正所苦，也就是俗称的近视，而台湾受近视折磨的人，比率可能是全世界最高的。因此，你可能会认为大多数的台湾人都戴着眼镜，但其实却不然。许多人反而依赖另一种方便的替代品──隐形眼镜。

The origin of contact lenses can be attributed to a man of many great inventions – Leonardo Da Vinci. In 1508, he wrote about aiding vision by submerging the eye in water, which would later serve as one of the basic principles behind the world’s first contact lenses. In the centuries that followed, liquid-filled “eyecups” gave way to glass contact lenses, and finally to the first modern lenses, which debuted in 1949.

隐形眼镜的起源可能跟一位伟大的发明家有关──那就是李奥纳多．达文西。他在1508年写下了把眼睛浸入水里来辅助视力的相关文章，后来就成了世上最早的隐形眼镜背后的基本原理之一。之后的几世纪，充满液体的「眼杯」被玻璃隐形眼镜取代，最后才让1949年首度出现的现代隐形眼镜给取代。

Today, there are many different kinds of contact lenses, which serve a variety of functions. Corrective lenses correct the imbalance between the refractive power of the eye and the length of the eye, allowing for optimal focusing of light onto the retina. There are also cosmetic contact lenses, which merely change the appearance of the eye.

现在的隐形眼镜种类繁多，有各式各样的功能。矫正用镜片能矫正眼睛折射力与长度的不平衡状态，让光在视网膜上的聚焦达到最理想的状态。同时也有仅会改变眼睛外观的美容用隐形眼镜。

Aside from daily disposable contact lenses, most kinds of lenses require regular rinses with cleansing and saline solutions. This gets rid of protein buildup and the various microorganisms. So, if you are one of the millions of people around the world who relies on contact lenses for better vision, remember to take good care of them so they can take good care of your eyes.

除了日抛隐形眼镜之外，大部分的镜片都需要用清洁液与盐水定期清洗。这样能去除掉堆积的蛋白质和各种不同的微生物。所以如果你身为世上数百万名依赖隐形眼镜来改善视力的其中一人，记得要好好照顾隐形眼镜，这样它们才会好好照顾你的眼睛。
