Every one of me has two of me.

AHA! Daily #001 · Wednesday 11 November · What am I?

The four clues

1. 1Every one of me has two of me.
2. 2A teacher faces thirty of me, or sixty, depending on how you count.
3. 3I shrink in bright light and grow in the dark.
4. 4I'm the black dot in the middle of your eye, and I'm also a child at a school desk.

In the game you get one clue at a time: solve it on clue 1 for 100 points, clue 2 for 75, clue 3 for 50, clue 4 for 25.

Why?

A pupil is a school student, and a pupil is the dark circle at the centre of an eye. So every pupil in the classroom has two pupils of their own: thirty at the desks, sixty looking back at the teacher.
