Myopia also has some effects on people’s mental health; wearing glasses will make people introverted. In the case of low vision, people usually dare not to say hello as they can’t clearly see whom it is.
If a child gets negative feedback after wearing glasses, his self awareness will also change over time; the self evaluation will fall and the character will become self-contempt, shyness. So people’s character will become introverted. But this case won’t happen in China or Korea because most of the kids there are myopia.
