ELI5: What does a blind person see?

Is it black? White? Does it make a difference if they are born blind vs. go blind later in life?

Someone told me people blind from birth literally see nothing (not black, literally nothing), but I'm having a hard time wrapping my head around that.

Close just one eye, and note that instead of seeing blackness like you do when you close both eyes, you instead see "nothing" out of the closed eye. That's what a blind person would "see"... nothing at all. Or simply imagine that other people had a sense that you lack, such as an ability to sense magnetism. When they asked you what you "sensed" when you tried to detect magnetism, what would you tell them?
