W: Hi. Tom. How things get along with the preparation for the annual meeting documents?
M: It’s coming along. But I’ve been staring at the computer screen for hours and my eyes hurt.
W: Yeah Typing the words on the screen really make your eyes dry and tired. You should take a break.
M: I can’t. The deadline is approaching.
W: You know, I read about computers and eye problems recently. The article says that they are usually caused by not blinking your eyes enough.
M: Blinking? I thought I just needed new glasses.
W: when you blink, the movement of closing and opening your eyes, even though it happens really fast relaxes your eyes.
M: That makes sense.
W: People using computer tends to stare at the screen and blink less often than they normally would.
M: That is what I am doing. And I am suffering from the dry eyes.
W: That is one of the typical symptoms. M: But what does it have to do with the computer?
W: The article I read about the office workers found that the workers averagely blink 22 times a minute when relaxed But just 7 times a minute while looking at the text on a computer screen.
M: Wow That’s quite a difference.
W: Yeah. So you need to blink your eyes and take a break from the computer
M: I wonder if using some kind of eye-drops will make me feel better.
W: That might help.But the best prescription is to take a break and rest your eyes
M: Ok. Let’s go get some coffee. I can finish this later tonight.
