W: Hi, Jack. How is your economics paper going?
M: It’s coming along. But I’ve been staring at this computer screen for hours and my eyes hurt.
W: Yeah. Doing that can make your eyes really dry and tired. You should take a break.
M: I can’t. I have to get this paper written. It’s due tomorrow.
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: No. When you blink, the movement of closing and opening your eyes, even though it happens really fast, helps moisten your eyes. It’s the lack of moisture that causes the problem.
M: That makes sense. But what does it have to do with the computer?
W: People who use computers tend to stare at the monitor and blink less often than they normally would. That leads to dry, irritated eyes.
M: Well, that’s certainly how mine feel now. They really hurt.
W: The article I read about the office workers found that the workers averaged 22 blinks a minute when relaxed. But just 7 a minute while looking at the text on a computer screen.
M: Wow. That’s quite a difference.
W: They also kept their eyes open wider which means the moisture evaporated more quickly.
M: I wonder if using some kind of eye-drops will make them 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.
27. What are the speakers mainly discussing?
28. Why is blinking important?
29. What should Jack do to improve his situation?
