Amazing Eyes

170299448_58cd484b32_mOur eyes are nothing short of amazing, astounding and awesome. Here are some facts about your eyes you might not have known:

  • Computer usage won’t damage your eyes. According to the American Academy of Opthamology, the feeling you have of eyestrain after using a computer has more to do with dry eyes than with actual strain. While using a computer, most people blink less often than normal, causing their eyes to dry out.
  • It’s very rare, but two blue-eyed parents can produce a brown-eyed kid and two brown-eyed parents can produce a blue-eyed kid.
  • Your eyes are not full size at birth. This one was a surprise even to me. At birth your eyes are approximately 16 millimeters wide and they grow to 23 millimeters by age three. They will be full grown at about 24 millimeters wide by the time you hit puberty—a size that is slightly smaller than a gumball.
  • The length of your eye determines what type of eyesight you have. Nearsighted people have longer eyeballs, while farsighted people have shorter ones. Even a change as small as a millimeter will change the prescription for your eyes.
  • Having 20/20 vision isn’t the same as having “perfect” vision. What it means is that you can see at 20 feet what an average person can see at 20 feet. The best recorded vision was about 20/10, meaning what most people can see at 10 feet, this person could see at 20 feet.
  • The visual center of your brain (the occipital lobe) is actually located in the back of your head. If you fall hard and hit the back of your head, it’s possible to go temporarily blind as a result.

How did our amazing eyes form? To fit the timeline of evolution, many evolutionists subscribe to the theory that eyes evolved spontaneously multiple times. This is the only way to account for the development of the eye in many different and divergent branches of the evolutionary tree.

But this isn’t a theory that makes much sense. The eye is only useful as a complete structure. What evolutionary advantage would non-functional parts have to cause them to evolve once, much less multiple times?

What makes more sense is that the eye is an awe-inspiring structure that speaks to the beautiful design of our creator.
