Few Interesting Facts About The Eyes!

The eyes are one of the most fascinating and complex parts of the body? The Bible declares in Psalm 34:15: “The eyes of the Lord are on the righteous, and His ears are open to their cry.”

That means that, just like you, God Almighty has eyes and He watches over the righteous, isn’t that great?

But how much do we really know about our eyes, and how they work? We use them every day, yet we haven’t given them much thought until now.

So, let’s look at a few interesting facts that you may not know about eyes!

1. Only one sixth of the human eyeball is exposed.
2. Our eyes are made up of over 2 million working parts, and the eyeball weighs around 28 grams.
3. The cornea is the transparent covering of the iris and pupil. Just behind our pupil is the lens – which is round, flat and thicker toward the middle.
4. Eyes are able to process 36,000 pieces of information in a single hour.
5. The human eye only sees three colours: red, blue and green. All other colours are combination of these.
6. Although our nose and ears keep growing throughout our lives, our eyes remain the same size from birth.
7. Eyes are the second most complex organ after the brain. Our eyes function like a camera, capturing light and sending data back to the brain. You see things upside down – it is your brain which turns the image the right way up.
8. In a single second, it’s possible to blink five times. You are likely to blink more often when you are talking. The eye is the fastest muscle in your body – hence why when something happens quickly, we say ‘in the blink of an eye!’
9. A blink typically lasts 100-150 milliseconds. On average, you will blink approximately 4,200,000 times in a single year.
10. The world’s most common eye colour is brown. Heterochromia refers to a condition where eyes are two different colours.
11. 80% of our memories are determined by what we see.
12. Oily fish, vitamin A and vitamin C can all help to preserve good eyesight.
13. Your eyelashes keep dirt out of your eyes, while your eyebrows prevent sweat dripping into your eyes.
14. It’s impossible to sneeze with your eyes open.
15. When you read or stare at a computer, you blink less often resulting in tired eyes. So, when working at a computer, you should follow the 20-20-20 rule – look at something twenty feet away from your computer every twenty minutes for twenty seconds.
