W: (21) 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. (22)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
