M: Good afternoon, can I help you?
W: Yes. [6]I’m here for an appointment at ten o’clock with the optometrist. I’m ten minutes early, though.
M: Are you Cherry?
W: Yes, I am.
M: I’m Simon, the optometrist here today. Please come in with me.
W: Thanks.
M: Before we test your eyes, I need to fill out this form here. So, what’s your full name?
W: Cherry Mars.
M: Have you ever had your eyes tested before?
W: Yes, but it was years ago, back when I was still in junior high. My eyesight was fine then.
M: But you’re having a little difficulty now, aren’t you?
W: Yes, [7]since I started at university, I’ve been having difficulty with distance vision.
M: OK, let’s have a look. Now I’m going to cover your left eye. Can you read the top line?
W: Urn... S... B... L... T... no, the last should be E.
M: Well, Cherry. Your eyes have obviously got a little worse and I think you’re going to need to wear glasses.
W: Do I have to wear glasses all the time?
M: It’s actually not that bad... not so much for reading or close work [8]but definitely for driving.
W: Right. I get it.
M: So now you need to choose some frames. There’re many beautiful frames to choose from. Please come over here.
W: Can you give me some idea of the differences among these frames?
M: Well, the prices vary enormously like everything else. The cheapest are the full frame. You can also choose frameless ones. Recently, it seems like those with the half frame are the most popular ones. They are also the most expensive ones.
W: Then what do you recommend?
M: I think frameless ones are quite good. [9]They are light, so you will not feel uncomfortable while wearing them. Besides, they are not as expensive as those with the half frame.
W: That’s a good point. I will follow your advice. Comfort always comes first for me.
M: That’s great!
W: When can I have my glasses, by the way?
M: Let me see. Today is Friday. If you pop back next Monday, I should have them ready for you.
W: Do I have to pay for them now?
M: You only have to pay half of the total price today, 36 dollars. And you can pay the rest next Monday when you come to pick them up.
W: Good. Is credit card ok?
M: Credit, debit, check, or cash. All are ok for us. But there will be an additional charge if you pay with a credit card.
W: Right. [10]I’ll pay in cash then.
