The Complex System of the Eye
Human sight is a very complex system of irreducibly complex interacting parts. These include all the physical components of the eye as well as the activity of the optic nerve attached to certain receptors in the brain.
Darwin himself wrote the following about the evolution of the eye.
‘Yet reason tells me, that if numerous gradations from a perfect and complex eye to one very imperfect and simple, each grade being useful to its possessor, can be shown to exist … then the difficulty of believing that a perfect and complex eye could be formed by natural selection, … How a nerve comes to be sensitive to light, hardly concerns us more than how life itself first originated; but I may remark that several facts make me suspect that any sensitive nerve may be rendered sensitive to light, and likewise to those coarser vibrations of the air which produce sound.’
The actual anatomy of sight is a wonderful example of what Intelligent Design theorists and Creationists call ‘irreducible complexity.’ The optic nerve is attached to the sclera or white of the eye. The optic nerve is also known as cranial nerve II and is a continuation of the axons of the ganglion cells in the retina. There are approximately 1.1 million nerve cells in each optic nerve. The optic nerve, which acts like a cable connecting the eye with the brain, actually is more like brain tissue than it is nerve tissue.
In addition to this, there are complex equations that the brain uses to transform what we see in real life onto the curved screen of the retina in the human eyeball.
This complex system is combination of an intelligently designed camera, lens, and brain programming all work together enabling us to see our world in incredible clarity.
Imagine having to use spherical shaped film instead of the conventional flat form of film in your camera. The images should be distorted. Just like those funny mirrors in the fun houses at state fairs and carnivals. That is exactly the way we see the world reflected against our curved retinas in back of the human eye.
We manage to correct these images and see them accurately without distortion because the Creator has installed fast-running programs in the brain that instantly correct the distortions in the image, so that the world around us appears to be flawless, like a photograph.
Not only that, the human brains turns our eyes, which are already more complex and refined than the most advanced High Definition cameras available today, into biological computers that can estimate the size and distance of objects seen. The objects are not measured as they appear on the retina, our brains act as an advanced evaluation program processing the physical data received by our sensory organs: it enlarges, reduces, and adjusts them precisely, so that the information is presented in a way that makes our sense of sight into an apparatus that is far superior to any pure instrument of physics.
It is this constant scanning and micro-computations that are being illustrated by the circular graphic in the article you are referencing.
Comparing the eye to a camera is an interesting analogy because our sight is really superior to an instrument of pure physics. Our eyes are able to see the darkest shadows as well as the brightest sunlight by automatically adjusting the optical range of operation. It can see colors. It can perceive white paper as being white, even when it is illuminated by bright light of varying colors. Our eyes contain the ability to perceive colors in essentially the same way. Color and shape are perceived as the same, whether the object is close or far away, even if the lighting varies radically.
The Creator, our Messiah Jesus Christ, is the infinitely intelligent Designer. His remarkable design of the human eye clearly speaks of His power and glory.
