问题 What are the speakers mainly discussing?
W: Hi.Jerry.How is your chemistry 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 fired.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 do I 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 I feel now.They really hurt.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 to get some coffee.I can finish this later tonight.
