I am a college student, I am short-sighted, which is better for me, buying common glasses, or buying contact lenses?

It is not good for students to wear contact lenst, first, the burden of heavy student learning, studends have to wear contact lenses for long time, affecting the metabolism of the cornea, the students study for long time and feel fatigue, they often sleep and easy forget to remove the contact lenses it is extremely bad for their eyes, second the contact lenses need good care. Students can not do well, and easily get their eyes infection .
