Technically the eye and brain are one and the same- as the eye is the only sensory organ besides the ears to have a direct connection to the brain. So the eyes are just extensions of the brain. All other sensory input must come through the spinal cord. The image is focused on the back of the eye in the retina, which in turn stimulates the optic nerve and relays the information to the area of the brain where it will be interpreted. Since one will not work without the other, I would say you require both to create vision.

Sight is an amazing process made possible by many parts of the eye working together. Light enters the eye and is bent or refracted by the cornea (the window of the eye) through the pupil (the opening in the iris). This light passes through the lens (located behind the pupil). This completes refraction by fine tuning the focused light onto the retina. The retina changes the light (energy) into electric impulses that are carried through the optic nerve to the vision center (occipital cortex) of the brain where the image is interpreted.

Both work in one accord.

both together, cones and rods in your eyes to distinguish color from black and white and nerves in your eye relay what is seen to your brain.
