I think scientists have done studies showing that the information coming in from the eyes are first filtered through some area in the brain before they are registered. That area can also be known as where the "ego" is physically manifested in the brain.
Dr. Hawkins once had his eyesight problems spontaneously heal itself and he had the realization that vision is a function of consciousness, not the physical eyes/brain. This is shown by how sight remains in OOBEs and astral projection, when your "body" isn't even there.
Watch a live hypnosis session and you'll be amazed. You can hypnotize someone into not being able to see some object, and they won't see it, even if it is right in front of their eyes. If beliefs can change perception like that, I think it's fair game to say that this is true in general as well, since we're all hypnotized to some degree.
There was this one story about hypnosis performed on a subject so that he wouldn't be able to see his daughter. The hypnotist then woke up the subject and put his daughter right in front of him, yet he couldn't see or hear her. The really crazy part is that he then held a watch
behind his daughter's back so that it was hidden, and asked the subject what he was holding in his hand. The subject nonchalantly replied, "a watch." The hypnotist then asked him to read the inscription on it, and he did perfectly.
Reality is perhaps more illusory than we've previously believed.
Very interesting stuff
