I am afraid of being laughed at by my classmates for wearing glasses. . . .

Ha! This mental state is normal. Being laughed at as a child often leaves serious psychological sequelae when you grow up.

If I were you, I would ask my classmates around me first. I'd better ask your friends if you wear glasses and ask them if they will look strange. If they say no, you can wear it directly to school. If so, ask them what they should wear if they have to wear glasses, and they will give you advice. You can buy glasses as suggested. If you have bought glasses, take them out and put them on, and tell people around you that I have glasses! Although this method is idiotic, it is better to speak first. You've reported it everywhere, and usually no one will point fingers.

It's okay, be confident!
