    Abstract:
    The first step of vision process is the ray of light approaching the eye .
    The middle step of vision process is the changes in the eyes and in the optic nerve,the electrochemical changes and other changes in the visual cortex and cerebral cortex or in the whole brain .
    Then,What is the final step of vision process?

    The final result of vision process is seeing the object itself when we observe a object .
    But,The brain can only produce a image of object,like TV,How can we see the object itself when we observe a object ?

    No doubt,The final result of vision process is confusing and also very magical.

    Where is the answer?
    Is the answer in the laboratory ?
    Or,Is the answer in the nature facts and physics facts?
    The Nature shows the answer of the final step of vision process itself!

    The virtual image have the character that it can be entirely overlapped(superposed) by the corresponding object .
    Only the virtual image itself can be entirely overlapped(superposed) by the corresponding object in the Nature.
    What happens when the virtual image is entirely overlapped(superposed) with the corresponding object ?
    The image here has dual identities, with one as a virtual image and the other a physical object.

    I pay attention to some physics facts which we do not pay attention to,Then,I cleverly reveal the secret of the final step of vision process with facts and irrefutable evidence.


    The final step of vision process How do we see?
    What is the final step of vision process?
    When we observe a physical apple,Is the apple which we see the apple itself,or is the apple which we see the picture produced by the brain?

    The Nature shows the answer itself.

    We see a virtual image in the plane mirror when our eyes and the physical apple are in the same side of the plane mirror .
    But,
    When the physical apple is placed in the position of the virtual image ,our eyes in the original position ,taking away the plane mirror ,What will we see again?
    According to the laws of image formation by a plane mirror ,
    The ray of light approaching the eye from the physical apple is completely indentical with the ray of light approaching the eye from the physical apple on the other side of the plane mirror through plane mirror reflection.The same ray of light approaching the eye produces the same vision result.
    The same ray of light approaching the eye produces the same vision result!
    The same ray of light approaching the eye produces the same vision result!
    The same ray of light approaching the eye produces the same vision result!

    So,When we obseve the physical apple which is placed in the position of the virtual image ,We see the second virtual image which is indentical with the first virtual image in the same position .
    So,The second virtual image is entirely overlapped(superposed) with the physical apple .
    The image here has dual identities, with one as a virtual image and the other a physical apple.
    Thus, as we see the virtual image , we are actually seeing the physical apple itself.
    We see the physical apple itself just through the virtual image of the physical apple and the overlapping(superposition) of this virtual image with the physical apple.

    And so on,The same way, We see the whole world just through the virtual image of the whole world and the overlapping(superposition) of this virtual image with the whole world.

    The overlapping(superposition) is the bridge of the virtual image and the physical object.
    The overlapping(superposition) is the bridge of vision cognition.





    Disscussion:
    1、The same ray of light approaching the eye produces the same vision result!
    isnít it so?
    This is a hard fact,This is the Truth,Who can deny it?
    Maybe we say: nothing plane mirror, nothing virtual image.
    No,It is completely wrong.

    The reason why we see a virtual image is the ray of light approaching the eye through plane mirror reflection.
    The reason why we can see is the ray of light approaching the eye.
    So,as long as the same light ,as the same vision result.
