So here we go again, another claim of a “perfect human design.” Today’s topic will be a little bit easier to grasp because we’ll be dealing only one human body part – the eye.
When we talk about “design’ that means a plan to emphasize a certain functionality. Example: We design a chair to look that way, because the purpose is for us to sit on that object. A cabinet is design to keep our things, a car is designed for faster mobility… and so on. Now in this Creationist’s post, he said that, “the eye must have been designed by someone who realized that it would be functioning in an atmosphere of dust and wind. It was designed in such a way to adjust to such conditions.”
Ok, so let see if he’s right – granted that we play along with his assertion that a “Designer” designed the eye so “that it would be functioning in an atmosphere of dust and wind.” According to his commentary, the eye was place in front of the face and the defenses (from dust and wind) are the following:
Let’s see the quality of each “defense.” I’ll be playing QA (Quality Assurance) to check the “Creator’s” work.
1. So the tears are there to lubricate the human eye against dryness. So what happened to the dust and wind? The tears attracts dust particle – no it doesn’t protect the eye against dust and wind. Dust stick to the tears and the wind dries it to form a goo where bacteria thrives. The tear glans’ opening is so small yet it is not protected against bacterial invasion – tada! Now you get “Pink Eyes.” Obviously, the Creator is not thinking well.
So why not create a liquid tear that instead of attracting dust from the wind, it will actually repel it? Or how about a natural lubricating system that is not exposed to dust and wind so it will not dry up with the dust particle? I remember this lizard that have 2 eyelids – the 2nd eyelids closes horizontally which wipes out dust from its eyes – that will be cool!
Conclusion: BAD DESIGN!
2. Now we go to the eyelids. The eyelids is said to protect the eye from dust. So we close our eyes in a dusty road – but the barrier is not fool proof – dust still enters the eye and worst, it attached itself just below the eyelids where you can’t reach it. It irritates the eye membrane and what do you do? Yep! You rub your eyes. So when you rub your eyes, the dust particle will scratch the eye, the thin eye membrane will be scratched and damaged and you get your eyes infected.
Your eyelid (thank you for the eyelashes) has these hairs (which are supposed to be an added protection) that detaches and enters your eye to become the irritant itself.
Why not create a natural eye shield – a dome like structure that will cover the eye from dust. A tough, glass-like membrane that doesn’t have hairs which are susceptible from breakages. This will cover the eyes from dust and dirt particles completely- something like the eye-shield of your expensive motorcycle helmet, complete with lens that darkens when exposed from too much light for added protection.
Conclusion: INCOMPLETE FUNCTIONALITY, BAD DESIGN!
3. The eye brows are there to protect our eyes from sweat? Darn, really? What a waste! If you will look closely on how your eyes are positioned on your face, you will noticed that it is slightly bulging. So when sweat travels from your forehead, gravity dictates that it will not go straight to your eyes but around it – in the same way where tears travel when you are crying… Duh? If the “Designer” have already placed it that way, what are the eyebrows for? It is just wasted material.
Conclusion: WASTEFUL, NO FUNCTIONALITY AT ALL. BAD DESIGN!
I give the “designer” a “D” for effort and “F’ for functionality.
The human eyes are located in front of the face – with a capacity of just viewing “the front view” – thus we cannot see anything at the side, on top, below or at the back of our body (unless we turn our head), and we’re bipedal, remember? This is not good when it comes from protecting ourselves from predators. A good designer should have supplemented this short-coming with a bigger eye with multiple lenses.
In the human eye, the visual nerve fibres (the nerves and blood vessels) lie on the surface of the retina instead of behind it. Therefore, the nerves dive through a hole on the eye’s surface which in turn, causes a blind spot. Squids and octopuses do not have this defect.
The eye’s photocells point away from the scene that is actually being looked at. As a result, light rays have to surpass a dense, concentration of cellular wiring in order to stimulate the photocells. This is like putting wires of a video camera in front of the lens.
So much for the Designer’s logic and if you call this “intelligence,” then you have to get your dictionary and look for the meaning of the word.
Oh here. I’ll make it easier for you…
