how eyes work

You have no idea what you're talking about.

We humans see light when its focused onto the retina of the eye by the lens. Light rays are perceived by our eyes as light enters - well, at the speed of light. I must stress the fact again that we live in an infinite world where information is continuously streamed to us. Our retinas interpret light in several ways with two types of cells; the rods and the cones. Our rods and cells are responsible for all aspects of receiving the focused light rays from our retinas. In fact, rods and cones are the cells on the surface of the retina, and a lack thereof is a leading cause of blindness.

  Calculations such as intensity, color, and position (relative to the cell on the retina) are all forms of information transmitted by our retinas to our optic nerves. The optic nerve in turn sends this data through its pipeline (at the nerve impulse speed), on to the Visual Cortex portion of our Brains where it is interpreted.

  Rods are the simpler of the two cell types, as it really only interprets "dim light". Since Rods are light intensity specific cells, they respond very fast, and to this day rival the quickest response time of the fastest computer. Rods control the amount of neurotransmitter released which is basically the amount of light that is stimulating the rod at that precise moment. Scientific study has proven upon microscopic examination of the retina that there is a much greater concentration of rods along the outer edges. One simple experiment taught to students studying the eye is to go out at night and look at the stars (preferably the Orion constellation) out of your peripheral vision (side view). Pick out a faint star from your periphery and then look at it directly. The star should disappear, and when you again turn and look at it from the periphery, it will pop back into view.

  Cones are the second retina specialized cell type, and these are much more complex. Cones on our retinas are the RGB inputs that computer monitors and graphics use. The three basic parts to them absorb different wavelengths of light and release differing amounts of different neurotransmitters depending on the wavelength and intensity of that light. Think of our cones as RGB computer equivalants, and as such each cone has three receptors that receive red, green, or blue in the wavelength spectrum. Depending on the intensity of each wavelength, each receptor will release varying levels of neurotransmittor on through the optic nerve, and in the case of some colors, no neurotransmitter. Due to cones inherent 3 receptor nature vs 1, their response time is less than a rods due to the cones complex nature.

  Our Optic nerves are the visual information highway by which our lens, then retina with the specialized cells transmit the visual data on to our Brains Visual Cortex for interpretation. This all begins with a nerve impulse in the optic nerve triggered by rhodospin in the retina, which takes all of a picosecond to occur. A picosecond is one trillionth of a second, so in reality, theoretically, we can calculate our eyes "response time" and then on to theoretical frames per second (but I won't even go there now). Keep reading.

  The optic nerves average in length from 2 to 3 centimeters, so its a short trip to reach our Visual Cortex. Ok, so like the data on the internet, the data traveling in our optic nerves eventually reaches its destination, in this case, the Visual Cortex - the processor/interpretor.

  Unfortunately, neuroscience only goes so far in understanding exactly how our visual cortex, in such a small place, can produce such amazing images unlike anything a computer can currently create. We only know so much, but scientists have theorised the visual cortex being a sort of filter, and blendor, to stream the information into our conciousness. We're bound to learn, in many more years time, just how much we've underestimated our own abilities as humans once again. Ontogoney recapitulates phylogeny (history repeats itself).

  There are many examples to differentiate how the Human Visual System operates differently than say, an Eagles. One of these examples includes a snowflake, but let me create a new one.

  You're in an airplane flying looking down at all the tiny cars and buildings. You are in a fast moving object, but distance and speed place you above the objects below. Now, lets pretend that a plane going 100 times as fast quickly flys below you, it was a blur wasn't it?
