Yael: How's it going, Don?
雅艾尔：唐，怎么样？
Don: OK, I guess.
唐：我猜还好。
Yael: What's wrong?
雅艾尔：出什么事了？
Don: Well, I've been getting headaches lately, and my neck and shoulders are kinda sore.
唐：哦，最近我一直头疼，脖子和肩膀也有点酸痛。
Yael: It sounds like you have the classic symptoms of computer vision syndrome.
雅艾尔：听起来你像是得了典型的计算机视觉综合症。
Don: Really? I can see why staring at a computer screen might strain my eyes for some reason, but why would that make my neck and shoulders sore?
唐：真的吗？我明白为什么一直盯着电脑屏幕会让眼睛疲劳，但为什么脖子和肩膀也会酸痛呢？
Yael: Because when you spend hours at a time at a computer, if you're not careful you can put a lot of strain on your entire body. So, for example, our eyes are good at focusing on the sharp black and white contrast of printed stuff like a newspaper. But characters on a computer screen aren't so well defined or sharp, so our eyes have to work harder just to focus. That strains the eye muscles and can cause headaches.
雅艾尔：因为当你花一个小时待在电脑面前，一不小心就会让整个身体备受压力。例如，你的眼睛能很好地集中在像报纸等黑白分明的印刷物上。但电脑屏幕上的文字却并没有那么明显清晰，因此我们的眼睛必须更加努力地工作。而眼部肌肉的拉紧就会导致头痛。
Don: OK. But there's nothing I can do about that, right?
唐：好吧。但我们对此也无能为力是吗？
Yael: True, but you can make things easier on your eyes. I'm guessing that your monitor is at eye level, right?
雅艾尔：是的，但你可以让眼睛看东西更舒服一些。我猜你的显示器与眼睛处于同一水平线上，对吗？
Don: Yep. And I try to sit up straight when I'm typing.
唐：是的。而且我打字时总是尽量坐直。
Yael: But those things are hurting your eyes. It's easier on the eyes to look down at something, like a book in your lap. Looking straight ahead is more difficult. And sitting up straight puts pressure on the spine. It's actually best to lean back slightly.
雅艾尔：但这样会伤害你的眼睛。眼睛朝下看东西会更容易一些，例如把书放在大腿上看。眼睛直视前方会比较困难。坐直也会给脊椎施加压力。其实最好的坐姿是稍微向后倾斜。
Don: I'll try it. I've also heard the using artificial tears and taking a break from staring at the screen helps.
唐：我会试试的。我还听说滴眼药水和适当的休息也起作用。
Yael: That's right. There are lots of other things you can do, too, like wearing glasses designed to help your eyes focus on the screen. You can find more tips by doing a web search for computer vision syndrome or cvs.
雅艾尔：说得对。还有其他许多办法可以尝试，比如配带专门帮助眼睛看屏幕的眼镜。你可以在网站上搜索更多有助于电脑视觉综合症的小贴士。
