Sam988 the research into the working of the eyes is fascinating and still ongoing as is research into the brain. What we thought we knew is only the tip of the iceberg and the discoveries being make are showing us that we are capable of much more. Some skills like PhotoReading are lets do it and see what happens and the proof that yeah it does work that way we can see it in the brain, comes later.
I think if you watch the DVD What the Bleep do We Know you'll learn there is a lot going on in our mind.
As Paul attempted to explain and they probably did a better job in down the Rabbit Hole, the eyes do not see it's the mind that sees.. The eyes are like camera's taking it all in and it's the mind that process the information. We have an agreement that what we focus on with the fovea is what the mind we are conscious of. Everything picked up by the eyes goes into the peripheral awareness. What we use primary focus on is our primary awareness and in our primary consciousness.
