14 interesting facts about human eyes

1. The eye muscles are among the most active forces within the human body because they move around one million times a day.

2. The human eye blinks approximately 12-times per hour. This means that we spend about 10 percent of the time closed with our eyes, and women blink twice as frequently as men.

3. Eyes of early human beings were brown, and the blue eye color is a relatively recent genetic mutation. Scientists believe that the source of blue eyes can be traced to the presence of a man close to the Black Sea 10,000 years ago and that the color green eyes are uncommon, considering that they only make up just 2% of the colors of the other watches.

4. two kinds of cells make up the human eye. One that allows us to perceive colors which are cone cells. The second kind of eye will enable us to see rod-shaped objects called rod cells.

5. Did you know that the eyes see things upside down? Yes, the eye can see everything upside down. However, the brain processes them quickly and then reflects the image to its proper location.

6. The eye cannot see the image clearly since it sees it as blurred and disorganized. But, each part of the brain absorbs part of an image and then stitches it together in the final stage to create a complete and clear vision.

7. The human eye cannot see red even though there are color receptors. This is because the receptors for red detect only green and yellow, and the green color receptors detect blue and green. However, the brain converts these signals into red color, and because of this, we can differentiate the red color.

8. Scientists have discovered that the cornea of the human eye is comparable to a shark’s corneas, and it is now possible to utilize the cornea of a shark’s eye during eye surgery.

9. The human eye ceases to grow after birth. Your eyes at birth are similar to how big your eyes are as you get older.

10. The vision of newborns is limited to black and white colors and certain shades of gray, and infants cannot focus on objects nearby.

11. Newborn babies do not shed tears when crying because tears don’t start to flow until about 3-4 weeks after the birth. The makeup of tears differs depending on the factors that trigger their shedding. The tears of irritation vary between crying or tears of lament.

12. The human eye can easily discern 10 million colors, and women are more adept than men at color perception because certain women are genetically modified, which allows them to perceive millions of additional colors.

13. Scientists have measured the precision in the eyes of humans and concluded that it’s 50 times more precise than a modern digital camera with an accuracy of 576 megapixels.

14. Peripheral vision is in black and white; however, the eye can fill the details of the surrounding area very quickly and then makes them color.
