Basically it comes down to the amount of light that can hit your receptors in the back of your eye.
Draw a circle to represent the hole where light enters your eye and hold it up in from of you. Now rotate it in any direction while still being able to see it.

It should look like it goes from something like this O to something like this 0.

Any way you turn it there is less light able to go through because you’ve decreased the surface area.
