Eye Exquisitely Designed

The closer we look, the more design evidence we see…

Evolutionists have long pointed to the vertebrate eye as proof of non-design. Consider these evolutionist pontifications:

The anatomy of the human eye shows that it is anything but “intelligently designed.” It is built upside down and backwards, with photons of light having to travel through the cornea, lens, aqueous fluid, blood vessels, ganglion cells, amacrine cells, horizontal cells, and biploar cells, before reaching the light-sensitive rods and cones that will transform the signal into neural impulses. – Michael Shermer

Any engineer would naturally assume that the photocells would point towards the light, with their wires leading backwards towards the brain. He would laugh at any suggestion that the photocells might point away from the light, with their wires departing on the side nearest the light. Yet this is exactly what happens in all vertebrate retinas. – Richard Dawkins, The Blind Watchmaker

“But I haven’t mentioned the most glaring example of imperfection in the optics. The retina is back to front. … “But now, suppose I tell you that the eye’s ‘photocells’ are pointing backwards, away from the scene being looked at. The ‘wires’ connecting the photocells to the brain run over all the surface of the retina, so the light rays have to pass through a carpet of massed wires before they hit the photocells. That doesn’t make sense … ” – Richard Dawkins, The Greatest Show on Earth

‘No engineer worth his salt would design an eyeball the way ours has been built.’ – Graham Phillips

But as usual, the truth can’t be kept hidden forever. Here are some important points to consider, with links to more details:

1. Our eye works better than any camera. How about a 10 billion to 1 dynamic range?

2. The location of the light sensitive cells must be in contact with a very rich blood supply in order to regenerate rapidly in response to intense light. This has been known for many years. Experts in eye function have pointed this out long ago. In fact, Dr. George Marshall (Ph.D. in Ophthalmic Science) wrote “The idea that the eye is wired backward comes from a lack of knowledge of eye function and anatomy.”

3. The incoming light is *not* interfered with by the layers it must traverse – and we should have known this since we can detect a single photon! In 2007 we learned that the Designer used fiber optics (Müller cells) to channel the incoming light to its target. This has been documented many places. In 2010, scientists wrote in Physical Review Letters “The retina is revealed as an optimal structure designed for improving the sharpness of images.”

4. Very recently (2014) its been discovered that the fiber optic mechanism is specifically designed to best support both our color vision (by rods) and our low light sensitive vision (by cones). This is well explained by Dr. Jay Wile who wrote:

The same scientists who published the 2010 study teamed up with two other scientists and continued to analyze the exquisite design of the retina. To understand the results of their new study, you first have to understand the difference between rods and cones. Both types of cells detect light, but the rods simply detect the presence or absence of light. The cones, on the other hand, detect color. Because they detect color, however, the cones aren’t as sensitive to light. In poorly-lit situations, then, your sense of sight depends strongly on the rods, and you don’t get a good sense of color. In well-lit conditions, the cones become more important, giving you excellent color vision as well.

Generally, speaking, of course, there is more light available in the day than there is at night. Thus, we can say that in general, your night vision is heavily dependent on your rods, while your day vision is heavily dependent on your cones. This means there is a trade-off when it comes day and night vision. For ideal daytime vision, all the light that hits your eyes should be directed to your cones. Of course, if that happened, you would have poor night vision. For ideal night vision, all the light that hits your eyes should be directed to your rods. Of course, if that happened, you would not have any color vision.

Well, it turns out that the Müller cells in the eye are exquisitely-designed to deal with this trade-off.

There are none so blind as those who will not see.

or as the prophet Jeremiah was told by the Lord:

Tell them: ‘Hear this,
you foolish people who have no understanding,
who have eyes but do not discern,
who have ears but do not perceive:
“You should fear me!” says the Lord.
…’
