Here some people will wear "OK" contact lens when they are nearsighted. It is a kind of hard contact lens. You just need to wear them at night and next morning your eyesight will be normal. Of course you have to wear them again when you are sleeping. Some people say that it is the only one way for your eyesight remains normal. If you put on glasses, then your nearsighted will become worse and worse. Have you heard about "OK" contact lens and do you think is it OK?

@nanachinese No, I am not going to let my son try use it as I think somewhat it is risky. Whereas I used it for myself long time ago and nothing went wrong. But I didn't want to take more risks. So I stopped using it after several years.
