Darwin wrote ...

In his “The Origin of Species”, he wrote: “ To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest degree.”

Even Charles Darwin realized how well designed the eye is and that was in 1859! He did not even know half of what we know now about the eye.

Below is an abstract from an article written by By Dr. Eric Lehr, Ophthalmologist. Indianapolis, IN

Perhaps the most amazing thing about the eye (and the brain) is the ability to process the visual information. John K Stevens has calculated that to simulate 10 milliseconds of the complete processing of even a single nerve cell from the retina would require the solution of about 500 simultaneous nonlinear differential equations one hundred times. Since there are millions of retinal cells, it would take the fastest supercomputer years to process what goes on in our eyes and brain many times a second.

What is even more amazing is that all these wonderful features of the eye are all interdependent on each other. For example, without the proper tear layer and eyelid function, the cornea would completely scar over. A functioning retina could be of no help if a clear cornea and crystalline lens were not present. And, of course, if the intricate organization of the nerve fibers in the eye and brain were not present, the eye would be rendered utterly useless. The idea that the human eye could evolve slowly over millions of years is absolutely absurd! Unless all the components of the eye actually “evolved” at precisely the same instant, the organ would be of no benefit!
