What's the use of blind people wearing glasses?

Hello, it doesn't make much sense for blind people to wear glasses. It's mainly for decoration. Because the glasses of the blind can't see, most of them have problems, that is, defects, which affect people's image. In order not to let others see the defects of their eyes, they wear glasses to cover up the defects of their eyes. Therefore, blind people wearing glasses only play a decorative role, which is the role and significance.
