10 Incredible Facts about the Human Eye – the human eye is so amazing and complex! So many things to discover!
I’m shortsighted, veeery, since I was 11 years old. I cannot be without glasses or contact lenses – or else I only see silhouettes. I am, actually, very very grateful to the ones who invented glasses and contact lenses (in 2004, it was estimated that 125 million people worldwide use them). Who doesn’t love seeing the beauties of the world, paintings, images! I have the biggest respect and sympathy for the ones who cannot see – I wish everybody could. I’m not saying that they have a bad life, just different. We can always find happiness in life. For me, one of them is to be able to see things. So I thought that a post about the incredible human eye would be good Did you know about the points below? Do you have any to add? I’d love to know more about the topic!
1. Maybe you have never thought of that, but eyes can also suffer sunburn. No wonder sunglasses must have UV protection!
2. If eyes were a camera, they would have nearly 576 megapixels!
3. The human eye distinguishes nearly 10 million different color shades!
4. Our retinas cannot detect the color red! Our retinas have red, green and blue colour receptors, but the “red” receptor only detects yellow-green and the “green” receptor detects blue-green. Our brains combine these signals and turns them into red! Here the full article.
5. About colors: the pigmentation of an iris can range from very light amber yellow to a very dark brown (55% of the world’s population), bordering on black. The darkness of the iris depends on its concentration of melanin. The greater the concentration of melanin, the darker the eye color.
– If you have blue eyes (8% in the world), you share the SAME ancestor with every person with blue eyes in the world – a person who lived close to the Black Sea more than 10,000 years ago, historians say. Blue eyes are more sensitive to light.
– Only 2% of the world’s population have green eyes or about 140 million people. Green eyes possess low to moderate amounts of melanin. However, green is actually not a pigmentation of the iris at all. And hazel eyes – that belong, in fact, to the green range – are completely different than other eye colors, with deep pigments of blue and emerald green. And that is my color
6. On average, we blink 17 times a minute. And 10% of our whole time we spend with eyes closed.
7. It is impossible to sneeze with open eyes
8. There is a phobia involving eyes: Ommetaphobia or ommatophobia. It is the fear of eyes. Sufferers would neither touch their eyes nor make eye contact and even by seeing eyes they will show anxiety symptoms.
9. Our eyes are almost the same size as when we were born.
10. Our tears show different composition based on feelings – if something makes us sad or if it’s just an irritation or yawning.
Wishing you a beautiful week with many smiles! Thanks for the sweet comments!
