Eyes are a gift. They are tools to interpret the world we live in.
Eyes are wondrously complex. A house fly has compound eyes. They are seriously compound. Between 3,000 and 6,000 simple eyes compose a single fly eye. The range of 3,000 tells us we really do not know how many eyes there are. These eyes work like thousands of TV monitors. Between the two compound eyes every fly has 3 ocelli. These provide the fly with navigational awareness. They keep the insect aware of which way is up. Perhaps one reason for such acute vision is the truth. The common house fly is food for many other animals, even the Venus Fly trap plant. Yet, these facts do not address the absolute phenomenon that fly vision is.
We intensify vision at least 10 times better than the house fly when the dragonfly is considered. Dragon flies and their smaller slower relatives the damselflies have up to 30,000 facets in each eye. This is like a human having 10-30,000 receptors spread across the retina. Actually, dragonfly vision is better than that because each facet has multiple receptors! The technical term for these receptors is ommatidia. Each receptor contains light-sensitive proteins called opsins. Daytime flying dragonflies have 4-5 different opsins. This allows them to see colors we humans cannot.
Look at the dragonfly eyes in the photo. Let’s estimate that a dragon fly has 15,000 receptors in each eye. That means that every split second there are 30,000 images coming to the dragonfly’s brain! Again, if it is a daytime flying insect it sees in colors even U-V light we humans cannot see. It is easy to believe that scientists do not understand how the dragonfly can process this massive mosaic of information.
People say the eye is the window to the soul. Human eyes do not function like the two insects we have discussed. Still, they are physical miracles. There are an estimated 2 million parts-in one human eye. More than 1 million nerve fibers that connect the eye to the brain-2 million with both eyes! It is estimated that 80% of what we learn we learn using our eyes. This is stunning.
One more thing. It’s about how we humans use our eyes.
Jesus said our eyes are the like a lamp. He described it this way, “Your eye is like a lamp that provides light for your body. When your eye is healthy, your whole body is filled with light. But when your eye is unhealthy, your whole body is filled with darkness. And if the light you think you have is actually darkness, how deep that darkness is. Matthew 6:22-23
The Bible calls life a race. When running a race the eyes of the runner are pivotal in the success of the runner. In the race of life, God provides us with these race instructions; “…let us run with endurance the race God has set before us. We do this by keeping our eyes on Jesus, the champion who initiates and perfects our faith. (Hebrews 12:1-2)
But, you say, I am so easily distracted. My eyes focus on other things. Relax, God is at hand, your hand. How close is that? Tell Him about your distractions. Ask Him to enable you to fix your eyes on Him. He will do it.
