Yesterday (October 8) was “World Sight Day,” a day set aside all over the world to promote eye health and to raise awareness for the struggles brought on by blindness and other visual impairments. It seems clear, then, that I should focus this week’s blog post on my Fun Fact about the human eye:
What makes the human eye unique?
The human eye is situated backwards so we don’t always have to look through a pool of blood.
I know there are a few ways I could go here, and you would probably see any of them coming: I could devote the next few paragraphs to the high importance of seeing the world clearly through the lens of the Bible. I could write to you about the ironies of 20/20 being hindsight, yet the year 2020 has taught us invaluable lessons on foresight. Or I could clarify the importance of a backward eye and highlight some of the other fascinating design features of our eyes. My choice: number three!
Why, exactly, are our eyes backwards? Technically, it isn’t the eyes themselves that are backwards, but the wiring. When you look at your eyes in a mirror, you see the beautiful “storefronts” that God has created, with the lenses, pupils, irises, and corneas. But behind those, there are photoreceptors that face the retinas, which are thin layers of tissue that line the backs of the eyes. When light hits the retinas, it activates photocells. These highly active photocells require nutrients found in the blood, so pools of blood are stored between the lenses and the photoreceptors, with the photoreceptors facing the back wall of the eyes. If the photoreceptors faced forward, or if the pools of blood were between the photoreceptors and retinas, our vision would always be tainted by those pools of blood.
But did you also know?
Matthew 6:22 (ESV) “The eye is the lamp of the body. So, if your eye is healthy, your whole body will be full of light...
