The writer contends and explains why the human eye is basically a fully functioning, self contained camera with a never ending supply of power. The eye functions mainly by permitting light to pass through the cornea which acts in the same manner as a camera's aperture.

From the Paper:

"Our planet is as it is because of the main function of the sun. The sun is the center and most likely the most critical part of our solar system because of the light it offers to feed our planet and drive all life. There is little doubt from a scientific perspective that our planet would be greatly altered without the sun and most likely would have no life. For living creatures to evolve, expand and thrive, they have had to learn to function on the ideas or concepts of sensing light in some way.
This notion applies to all living creature on our planet and therefore could be considered to be an almost universal law. Consider that all plants utilize light through the concept of photosynthesis to feed themselves and mammals and other life forms utilize light to hunt, mate and preserve themselves through the cycles of light that are present."
