W: Hi, Tom. 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 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: I guess so.
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.
