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
