May: Good evening. I'm looking for a pair of contact lenses.
Clerk: All right. Do you know your eyesight?
May: 300. I just had my eyes tested last week, so it should be precise.
Clerk: Did you wear contact lenses before?
May: No. But I'd like to try. Will it be troublesome to wear contact lenses?
Clerk: No. They are more convenient than ordinary glasses. But contact lenses are not suitable for everyone. Individuals with dry or sensitive eyes lost their ability to wear contact lenses.
May: Luckily, I don't have those problems. My eyes may be a bit weak, but they are healthy.
Clerk: Good for you. Here's a selection of lenses. Please take your time to have a look and pick out some you like. They all have descriptions on their packing boxes.
May: I see. Oh, I like this blue pair. May I try them on?
Clerk: Sure. Let me bring you a new pair. Please wait for a while.
(The clerk brings a pair of blue contact lenses.)
Clerk: Here they are. Sit in front of the mirror please and try them.
May: Very comfortable! It was a piece of cake! By the way, is there anything that I should pay extra attention to?
Clerk: Yeah. Always wash your hands before handing contact lenses. You should always keep them clean since they go on your eyes.
May: May I clean them with tap water?
Clerk: No. Here are some multi-purpose solutions for you to use. Carefully and regularly clean your contact lenses after each use. Here are the recommendations for Contact Lens Wearers. Make sure you read every item and follow them.
May: I went to a glasses store today to get a pair of contact lenses, for I think they should be more convenient than ordinary glasses. But the clerk told me that contact lenses were not suitable for everyone. Luckily, my eyes are just with them and there were quite a variety of beautiful contact lenses for me to choose. I picked up a blue pair and went home happily.
