Which treatment do they think is the most effective?
Conclusion In this project, we find so many people dont 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 wont 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.
