10 Things You Didn’t Know About the Human Eye
June 7, 2017
Our eyes may be small, but we can all agree they’re pretty essential. Not just to be able to see and understand the world around us, but to communicate, absorb, and express. Many cultures believe they’re vessels into the soul, but at the very least they’re vessels into our outside world. In light of the Phillip and Patricia Frost Museum of Science ‘SEEING: What are you looking at?’ exhibition and our upcoming LATE @ Frost after-hours jam on the 14th, we’re breaking down some pretty darn interesting facts about our pair of portals. Check them out below:
THEY’RE CONSTANTLY ON.
When waking up in the morning or even standing up after a long period of time, most parts of your body take a little time to warm back up before getting to their full potential. Your eyes, however, are on their A-game 24/7 and the muscles that control them are the most active in our bodies.
THEY TAKE UP HALF YOUR BRAIN.
Seeing, and the energy it takes to control the muscles that allow it, are so important that they take up half our brains to run smoothly (or at all).
YOU HAVE BLIND SPOTS.
Each of your eyes has a small blind spot in the back of the retina where the optic nerve attaches. You don’t notice the hole in your vision because your eyes work together to fill in each other’s blind spot.
THEY’RE A COLLAGE OF SORTS.
The cells in your eye come in different shapes. Rod-shaped cells allow you to see shapes, and cone-shaped cells allow you to see color.
THE LENGTH OF YOUR EYE MEANS EVERYTHING.
Being nearsighted or farsighted depends on the length of your eye. – People who are nearsighted have longer eyeballs while those who are farsighted have shorter ones. It all comes down to about a millimeter of difference in size.
YOU CAN SEE UPSIDE DOWN.
The way our eyes are structured causes us to perceive everything as upside down. When our brains process images, however, they become right-side up. This process occurs so rapidly that we don’t even notice.
IT’S A COLOR DETECTOR.
The human eye can interpret over 10 million different colors. Whether the dress is blue or black, that’s pretty frickin awesome.
YOUR EYES ARE ON THE BACK OF YOUR HEAD.
The “visual centers” in your brain are actually located at the lower back part of your head. The optic nerve begins at the back of the eye and, through a series of connections, relays the visual images to the occipital cortex in the very back of the brain.
THEY KNOW WHY YOU’RE CRYING.
Your eyes create different chemical makeups in tears depending on your reason for the water works to make sure your body is still nutrient balanced. Protein-rich tears to ease your heartbreak, easy tears to flush out the toxins of onions, and of course tears full of Basal to keep them protected.
THE EYE HAS OVER TWO MILLION PARTS.
The optic nerve alone has over a million fibers, which makes it too sensitive for a successful transplant. But the rest is dedicated to its function which, if we haven’t established already, is pretty complicated.
