It blocks the teacher's view of your face so he/she can see if you're sleeping or not...
My teachers can't tell when I'm sleeping anyway.

Have you and your parents ever considered an alternate form of education ? I always thought America allows for non-standard education models and as you seem to have trouble following basic social norms and are apparently either not interested or bored by what goes on in the classroom, maybe this just isn´t the right environment for you ?
Edit: Just on a personal note, because I hear this "the teacher can´t tell anyway"-thing pretty often. Having taught a couple of tutoriums at university, I feel I can say this with some authority:
The teacher can tell. Always. At a glance.
They also hear most whispers, even those coming from the back (though usually not what is said, just that something is said). This is due to the position of the teachers in the classroom.
Most of the time, it is a deliberate decision to ignore it, as confronting the student is way more trouble than its worth, usually.
