About Our Amazing Eyes

February 17, 2020

Our eyes are an utterly astounding achievement of hundreds of millions of years of evolution. We take what they do for us every waking moment of the day for granted, for the most part. It is just how we function. But how much do you really know about your small but mighty eyes?

Let's take a look at some interesting facts

Our eyes are only about an inch across and only weigh about 1/4 of an ounce. Your eye is made up of 107 million cells and has 2 million working parts.

You actually view things upside down, it is how our eyes function. Our brain is the part that flips them back the correct way.

Think we just see the six colors of the rainbow? Think again. Depending on who you ask, our eyes can see seven to ten million - yes, million - different colors.

But supposedly we see three main colors: green, blue and red. The rest are just combinations and variations of these three.

What color is your favorite? Or which do you dislike? Red and yellow are apparently the most irritating colors to our eyes.

Know what the cornea is? Do you? It is the clear covering over your pupil and iris. And the shark cornea is so similar to the human cornea, it has been used in eye surgeries!

Your eyes can deal with about 36,000 images or information per hour, and will see about 24 million different images in an average lifetime.

Your ears and nose may slowly grow over time, but your eyes remain the same size.

When you look at something, do you feel a delay between the moment you first see it and when your brain acknowledges what it is? No, because it only takes 13 milliseconds for our eye to process the images we see. Lighting fast!

Wonder why eye scans are used for identifying people? Your iris has 256 different characteristics, whereas your fingerprint just has 40. Your retina is incredibly unique!

How many times do you blink? The average person blinks 4,200,000 times per year!

Why do we have two eyes and not just one? Having two eyes gives our brain two images to compare and then determine the distance of what we are looking at.

The red eye in pictures is caused by when the light bounces off the capillaries located in your eyes.

We haven't yet been able to receive eye transplants, due to the high sensitivity of the optic nerve. But, never say never!

Eyebrows and eyelashes exist to keep sweat, dirt and dust out of our eyes.

Cells are constantly replaced in our bodies. Except for our eyes. They exist from birth to death.

Eyes can heal quickly. A cornea that is scratched can heal in about 49 hours.

Hear of people saying babies can't see or don't know you yet? Well, it does take roughly three months for infants to begin to recognize familiar faces they see often.

The sun doesn't just affect your skin. About 94% of premature again for your eyes comes from UV damage. Get a pair of sunglasses!

Think you run fast? Or can throw a fastball? Nothing beats your eye, though. It is the fastest muscle in the body. Your eye's muscles are 100 times stronger than needed to work correctly.

Doctors believe about half of the human brain works for vision and eyesight. And the brain is the only part of your body more complex than your eyes.

Your eyes are always ready for action. Any time of day, with no rest, they will do their job.

Memories are mostly made of what we see. 80% of memories come from eyesight.

Don't believe the wives tale of a parent having to have blue eyes if a child does. It is a recessive trait that can skip a few generations and still occur.

Two different colored eyes for one person is called heterochromia.

We have blind spots, where our optic nerve goes through the retina. Our brain has found a way to compensate for this, by using info from the other eye to fill in the blank.

Get scared or frightened? Your eyes will automatically close to protect themselves.

Doctors know tears help to clean eyes, but still don't know what the connection is with tears and being sad. But if your nose is runny when you cry, it is because tears are also drained into your nasal passageways.

Compare your eyes to a modern digital camera and it would equal 576 megapixels.

How far can our eyes see? Well, this also depends on who you ask. A healthy eye can spot the faintest glimmer of a candle from about 1.5 miles away. But some say it can be as far as up to 14 to 30 miles away. Seems way too super-human, to me!

Do you know someone who is blind? There are about 39 million humans who are completely blind, so chances are you might know someone. However, 80% of the vision impairment around the world can be avoided or cured.

Have a fear of eyes? It is rare, but ommetaphobia is the fear of the eyes!

Practice the 20-20-20 rule. This is recommended by doctors and specialists for people who use computers or screens daily. Every twenty minutes, look away at something about 20 feet away for roughly 20 seconds. Just give your eyes a little break!

All so very incredible. Now you know why doctors want you to eat healthy and care for your eyes. They are truly precious marvels of our human bodies.

And with all our eyes can do for us and continue to offer us, we should give back a little and do our best to keep them as healthy as possible. Schedule an appointment for you or your child today to keep your eyesight as clear as possible. You might not be able to see a candle 30 miles away, but keeping your eyes healthy is still very important.
