A、How to operate the computer. B、How to have a break after work. C、How to choose the right glasses. D、How to avoid eye problems

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 makes 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 tend to stare at the screen and blink less often than they normally would.
M: That is what I’m doing. And I’m 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.
