    The reflection being further is the point? The further away something is, the smaller it looks, so the less of your field of view it takes up, the more you can see of it.

    If I put my hand on my eye, I can’t see much of it. If I pull my hand back, I can see more of it. If I put a mirror on my eye, I can only see my eye. If I put it back, I can see my face because the reflection of my face is further (i.e. smaller).

    I’m very confused what you’re trying to say.

      Ok, visualize it like this:

      Draw yourself, with a small mirror at head height, a meter away. Draw your reflection at the same distance from the mirror on the other side.

      Now do that again, but place the mirror 10 times further. Then draw lines from your eye, to the edge of the mirror, and to the reflection.

      You’ll reach the same point on your reflection.
