MIRACLE IN THE EYE


            ing, a chemical substance forms that stimulates the nerve cells. Rhodopsin
            loses its property in bright light, but reforms again in darkness.
                When you enter a movie theater, for example, at first you will be unable
            to see clearly, because at that moment, there is not enough rhodopsin present
            in your eyes. Once more rhodopsin is produced, your vision clears. You won't
            be able to see clearly until enough rhodopsin is produced; but once the
            rhodopsin balance is maintained, you'll find it easier to distinguish objects in
            the dark.
                Once you leave the cinema and walk back out into the sunlight, however,
            rhodopsin breaks down rapidly, sending many signals to the brain at once.
            Objects in your vision become unusually bright, making it difficult to see. In
            bright light, rhodopsin breaks down faster than it is synthesized. That's why
            your vision seems defective for a while. Again, rhodopsin is why your eyes are
            dazzled by the sunlight and the snow. Once most of the rhodopsin is de-
            formed, fewer impulses are transmitted to the brain; the eyes have become
            light-adapted. 10
                Rhodopsin, when needed, is produced at just the right amount. It works
            in conjunction with the other parts of the eye, allowing us to see easier in the
            dark. But who first decided to produce this substance? Did eye cells, unable to
            see in the dark, spontaneously gather and decide to make a substance that en-
            hances vision in the dark and breaks down in brighter light? Supposing that
            they did so, then who designed rhodopsin's physical and chemical structure?
            And how did the eye cells gain all the genetic information they need to work
            with rhodopsin?
                There are far more details to the process of seeing than we've described in
            these few paragraphs. But rhodopsin by itself is an accurate demonstration of
            what a miraculous system the eye truly is. Clearly, its cells didn't develop
            rhodopsin on their own. The eye, with its delicately calculated system, is a cre-
            ation of God.

                The Primary Colors

                As we mentioned earlier, the cones within the retina are those cells that
            perceive colors. There are three separate groups of cones, each of which reacts
