[LOTR] Why doesn’t the one turn Sauron invisible when he wears it?

Because he controls the ring rather than it doing whatever it wants and he's already in the spirit world. The ring kind of drags people half into the spirit realm which is why they turn invisible to mortals. Something like gandalf and sauron and sarumon can still see them plain as day because they have a foot in the spirit world by their very nature.
