Your camera takes great pictures: One of the least favorite phrases any photographer wants to hear. It implies that somehow the photographer’s camera has auto-magically created an amazingly composed, stunning photograph without any human intervention or skillset whatsoever. But wait. There is a camera like that, and most people own one! It’s called your eyes. Our human eyes are controlled by a set of amazingly sophisticated, finely tuned, very delicate set of controls that acclimatize to different lighting conditions.
As one dives deeper into understanding light, it’s hard not to chuckle at the mere thought of all these things accidentally happening by random chance. I mean, I don’t want to offend people who think that the world just evolved from a fluke set of coincidences. But as you dig into the science of it all, the sheer amount of evidence pointing to intelligent design is impossible to ignore. Dare I say that you’d have to have your eyes closed not to see it.
So how complex and wonderfully created are our eyes? Let me just give you a very small glimpse as to what it takes for you to see anything.
To even entertain the possibility of physical sight, light needs to reach your retina, a thin layer of tissue that resides on the back of your eye near your optic nerve. The retina’s responsibility is to take the light from your eye lens, translate it to neural signals, and then fire it off to the brain (which is a whole other insanely complex matter). We could just stop there and say, “yeah right, there’s no way that’s possible,” but it is! So, let’s just take a small snapshot of what needs to happen for you to be able to see.
To begin, the amount of light that enters each one of your eyes needs to be measured and controlled. Think of an over-exposed or under-exposed photo—too much light, and you can’t make out anything; too little light, and you’re facing the same problem.
Secondly, the subject needs to be sharp and in focus for the brain to understand what the heck is going on.
Starting at the front of your eyes, we have the cornea, an advanced, transparent tissue that helps bend light into focus. Next, we’ve got a clear fluid called aqueous humor, which also helps bring light into focus. Following that we have the iris (responsible for your eye’s coloring) and the pupil, sitting virtually in line with the cornea. Like camera aperture when you take a photo, the iris (which in Greek means rainbow—think visible light spectrum that we already discussed) controls how much light enters the eye by automatically increasing and decreasing the size of the pupil opening. Wait, what? Are you kidding me? Nope. The best Inventor in the universe invented the best, most beautiful camera in the world.
Continuing along, as light passes through the cornea, aqueous humor, and pupil, it finally gets to the lens which—based on how the brain views it—does the fine adjustments for both near and far focusing. Finally, the light flows through the vitreous humor (a jelly-like substance) and reaches the retina, en route to your brain. Unbelievable, right?! If that’s not enough, there’s another player here—the muscles in your eyeballs move them up, down, left, and right to allow you to look precisely at what you want to see. You can’t make this stuff up.
If one of these things—the cornea, the pupil, the aqueous humor, the iris, or other numerous parts of the eye—isn’t functioning, you can’t see. It’s really that simple.
On top of that, having two eyes gives us the ability to see with binocular vision, providing us with amazing depth perception. As an example, you wouldn’t want to thread a needle with one eye open and one eye closed; it would end badly because your perception of depth and location requires two eyes to function properly.
That photographer’s camera you thought took amazing, auto-magical pictures is like a child’s toy compared to what God has designed in our eyes. To Him be the glory.
For this people’s heart has grown dull, and with their ears they can barely hear, and their eyes they have closed, lest they should see with their eyes and hear with their ears and understand with their heart and turn, and I would heal them. (Matthew 13:15)

Do we see the amazing beauty in the things that God has created, the people He's brought into our lives, the situations He's put us in? Or do we live in a bubble, oblivious to His amazing wonder happening all around us? unOblivious is a 160-page photo-essay that helps answer that question.
