It doesn't. Like stopping down a camera lens, looking through a pinhole or other small aperture increases your eye's depth of field. That lets you focus closer, so you can get closer and the object looks bigger.

It acts like a pinhole camera. And thus, it makes the image clearer if you have bad eyesight.

Hi w_earps ,
It doesn't really. It simply concentrates your view on the subject with less distractions.
