    Becasue the holes in the card force the light get back futher and focused to a point which makes it reach the back of your eye, just like how the eyeglasses work.

    Just like pin hole glasses, when you look through the glasses with many holes in it, only a small amount of light can go into your eyes,so it forces your eyes get into focus and then make your eyes see things clearer.

    I don't know how to explain it but you may have the similar experience.When you look at something through a small hole,you will see more clearly.I think they are the same theory.

    I think it is just like how glasses work.The holes force the light to refract and reach the point in the back of your eyes where it should be.
