For quite some time, many years in fact, evolutionists like Dawkins who wrote a book, The Greatest Show On Earth…argued and mocked creationists that the human eye was obvious proof for evolution because it was based on a bad design. Dawkins and others have claimed the human eye’s nerves should have been wired in the back rather than the front. Which ophthalmologist was he and others consulting while coming up with such an absurd hypothesis against creationism and intelligent design?
In back of the eye is the choriod which would block the wiring. In order to prevent that from happening and still be able to wire the eye from the back, the choriod would need to be moved to the front. This would cause hemorrhaging because the choriod is opaque. Also backward wiring would cause a disconnect with the photorecptors with RPE and choriod. It’s very important to have the connection because it would remove the eye’s ability to absorb heat which means we would go blind for weeks on end if we looked at bright light. So backwards wiring is not a better design for the human eye.
What about the human retina that appears to being placed in the eye backwards, is it still a bad design? Back in 2007, German scientists at Leipzig University discovered a layer of cells that act like another lens inside the eye, channeling the light right through the opaque layer and putting it right where it is needed.
The commentary reflects…
“They have demonstrated that light is collected and funnelled through long cells called Müller cells. These work almost exactly like a fibre optic plate: a “zero-length window” that optical engineers can use to transmit an image without using a lens….Everyone thinks lasers are perfectly parallel, but this is not so,” [Andreas] Reichenbach continues. “They do diverge. The Müller cells behave as a lens, and collect all the light without any loss, just like an optical plate.
But normal optical plates have simple bundles of optical fibres that collect and transmit the light. The researchers have discovered that the vertebrate eye has gone one step further and created a funnel shaped cell that allows more light to be collected at the surface of the eye….“Nature is so clever,” Reichenbach says. “This means there is enough room in the eye for all the neurons and synapses and so on, but still the Müller cells can capture and transmit as much light as possible.”
It’s funny how they call an unthinking process, “clever” and it’s also interesting to note that some evolutionists are starting to come to grips with the fact that the human eye is a good design while others argued that it was only a makeshift correction as a result of natural selection. It doesn’t stop there as more discoveries have been made, one of which happened this year concerning these very Müller cells by a team the Technion-Israel Institute of Technology in Haifa
“At least two types of light get inside the eye: light carrying image information, which comes directly through the pupil, and “noise” that has already been reflected multiple times within the eye. The simulations showed that the Müller cells transmit a greater proportion of the former to the rods and cones below, while the latter tends to leak out. This suggests the cells act as light filters, keeping images clear.”
“The researchers also found that light that had leaked out of one Müller cell was unlikely to be taken up by a neighbour, because the surrounding nerve cells help disperse it.”
“What’s more, the intrinsic optical properties of Müller cells seemed to be tuned to visible light, leaking wavelengths outside and on the edges of the visible spectrum to a greater extent. The cells also seem to help keep colours in focus. Just as light separates in a prism, the lenses in our eyes separate different colours, causing some frequencies to be out of focus at the retina.”
“The simulations showed that Müller cells’ wide tops allow them to “collect” any separated colours and refocus them onto the same cone cell, ensuring that all the colours from an image are in focus….”
We now know keeping photoreceptors in back near the blood vessels is a marvel of engineering design as it provides optical advantages. It’s performance is beyond our scope to duplicate. While evolutionists continue to argue on what they deem as a bad design (as they try to get inside God’s mind on motive) and a non-thinking process being able to improve a bad design, it cannot be rescued from the fact that what they are promoting is merely a science fiction story.
