Nick Nolte is campaigning against 3D television because he's convinced it's bad for viewers' eyesight.
The Warrior star is awaiting a scientific study that will prove he's right to be concerned.
He tells WENN, "3D actually disconnects the eyeball from the lens from the brain, so that whole system doesn't function.
"They're finding out it causes psychotic states. It's, like, the brain, itself, is creating a hallucinative (sic) agent of 3D. But when something is close, the lens doesn't change. If something is far, it doesn't change because you're looking at a two dimensional plane.
"They're going to find out six hours of 3d Tv will cause a psychotic affect. Australia is doing the research. I can just tell you that."
