What do people mean by “you don’t see darkness, you see nothing” if you lose your eyeballs?

Question

I cannot fathom seeing nothing as opposed to just seeing pitch black. An example I was told is “it’s like trying to see out of your elbow”. I still do not get it

Let’s if I can crack it down.
If you close your eyes, you see darkness. How dark it is, depends on the amount of light in the room. Even if you close your eyes, you still have some “light”.

But if there are no eyes to receive any form of light, then there is no darkness, there’s nothing. Nothing is not darkness or anything. Nothing is nothing.

If you lose an arm, you might get a phantom arm and sometimes feel your arm is there, but if you were born without 1 arm then all you know is 1 arm and nothing else. To the 1 arm borned person, there is no 2nd arm, there never was, there is nothing.

Fuck, I can’t explain it.
