Proverbs 4 8-4-22

As we continue our journey through the human body and its intelligent design, we look again at the human eye.

20:12 Ears that hear and eyes that see–the LORD has made them both.

Yesterday, I listed the main parts of the eye: the cornea, the iris, the pupil, the lens, the liquid, the muscle, the cleaning system, the retina, and the optic nerve. Let’s look at each of them.

  • The Cornea- the thin covering over the front of the eye. It is about four times more powerful than the lens in bringing light into focus.
  • The Iris- the colorful part of the eye. It has two sets of muscles that work together to open and close the iris diaphragm thus controlling the size of the pupil. One muscle within the iris constricts the pupil in bright light (full sunlight, for example), and another iris muscle dilates (enlarges) the pupil in dim lighting and in the dark.
  • The Pupil- the window of the eye, it is how light enters the eye and focuses on the retina.
  • The Lens- flexible like rubber, it can quickly focus by changing its shape. Like the cornea, it is derived from embryonic skin and is marvelously transparent.
  • The Liquid- There are two kinds of liquids in our eyes, the Aqueous Humor and the Vitreous Humor. From Georgiaeyephysicians.com,

The Aqueous Humor- Inside the eye are several compartments, or chambers.  Two of those chambers, the anterior (between the cornea at the front of the eye and the iris) and the posterior (between the iris and the lens) are filled with a thin, watery fluid called the aqueous humor.  After being produced by the ciliary body, the fluid flows through the pupil to fill the anterior and posterior chambers, after which it drains out of the eye through a structure called the trabecular meshwork. 
The Vitreous Humor- About eighty percent of the space inside the eye, the area behind the anterior and posterior chambers and between the lens and the retina, is filled with a clear, gel-like substance called the vitreous humor.  Consisting mainly of water, with small amounts of collagen, proteins, salts, and sugars, the vitreous has a firm, jelly-like consistency and helps to maintain the eye’s spherical shape. 

I know it’s a lot of information, but we’re not done, yet. Tomorrow, we will cover the muscles, the self-cleaning system, the retina, and the optic nerve. And to think that this visual system is contained and controlled by the DNA in every person’s body…definitely a Master Design!

Abba, the eyes with which we see are strictly physical. You look with Your spiritual eyes at our hearts and minds. May we learn to trust You to help us adjust, fix and censure what we see with our physical eyes along with the “eyes” of our heart and mind. Amen.
