ConclusionIn this project, we find so many people
don’t know how to choose the best rectifying method to treat their eyesight. They only think if the method is convenient or cheap, then they would choose it. Some people think that the methods were dangerous, they won’t choose it! People affected by the propagate advertisement to choose this method for themselves. Most people choose to wear contact lenses but it has bad side effect on their eyes. So we do this project to tell other people how to choose their rectifying methods of eyesight.
Reflection of each group member Group Leader :Lam Man Ting, Eugenie (11):
We use long time to do this project , because we want to make a perfect project. The project is finished. I learnt so many things from doing this project. For example, How to set up a questionnaire, how to share and be fair among the group members. By the way, I know more about the eyesight problem, not only follow the tidal current to choose the rectifying method of eyesight for myself. Thanks my group members and teacher adviser to give me this experience. Thanks all!
Group Members : Ho Yuk Chu ,Carol (9):
I am relaxed about the project has been finished. I enjoy analysing the project. I like this challenge. I have a chance to interview at street .It is quite challenging. I have learnt the skills to interview people. One thing I want to mention is how to divide the work and finish it in an efficient way. I hope you will be interest in our project topic! Thank you!
Lam Ming Chun , Monique (12):
After I finished this project, I know more about the knowledge of eyes and the method to improve the eyesight problem. Besides this, I learn how to work with other group members. I think cooperation is very important. That’s all. Thank You !
Law Miu Chi, Nicole (16):When we are doing this project, I learn a lot of things, such as set up questionnaire and some information about LASIK. But I also have some mistakes. I have done my work too slow. If I do next project, I would do as fast as possible.
Mo Hoi Sze, Hazel (21) :
I have learnt many things in this project. I knew that cooperation with my classmates is very important ,because we cannot finish the project just by myself. We need to cooperate and help each other. Also, I learnt how to solve difficult problems . It is useful to have the project skills when I go into society and interview with others. Besides that, I have known a lot of things about eyes.
