The 18 secrets of the eye

Love eye and eye protection, start from childhood

Each eye has 17 million cells. Only 7 million of those can tell color and detail, while the remaining 100 million can only tell black and white. That means less than one in ten of the cells in all eyes can help us see the color. The eye is a complex and magical organ, and the vision prevention and control research and development center Xiaobian together to understand the eye.

1. Eyes will change color

Like the sky, the color of the eye adjusts according to the brightness of the light. This change is particularly noticeable for the light eyes.

2. People with blue eyes may have the same ancestor

Each blue-eyed person most likely came from the same ancestor. The first person with blue eyes lived around 6,000 to 10,000 years ago. Before that, everyone had brown eyes.

3, with 17 million cells per eye

Each eye has 17 million cells. Only 7 million of them can distinguish between color and detail, while the remaining 100 million can only distinguish between black and white. That means less than one in ten of the cells in all eyes can help us see the color.

4. The brain automatically corrects the image you see

If you wear a pair of glasses that will turn the picture upside down, your brain will get used to it and eventually let you see the picture coming up.

5 blinking is amazing

Our eyes blink, on average, 17 times a minute, blink 14,280 times a day, and blink 52 million times a year.

6. Have the fastest muscles

People often say "blink of an eye" time to describe the time flies, this is actually for a reason. Because this is the fastest muscle in our body. Each blink time is about 100 times to 150 ms, that is, blinking five times a second is possible.

7. When you get old, you may need to wear glasses

99% of people need glasses to see clearly between the ages of 43 and 50. This is because the crystals of the eye slowly lose the ability to focus with increasing age.

8. Eye crystals will focus faster than any camera

Please look around if you see that your eyes can quickly focus on things at different distances when you are simply unaware. This is really very fast compared to the camera speed oh oh.

9 Diabetes is often detected for the first time during eye examinations

Patients with type II diabetes often have no obvious symptoms. So it is often found during the eye examination, because they will have a small amount of fundus bleeding phenomenon.

10. Seeing things is the result of both the eyes and the brain

We're looking at things with our brains, which may sound weird. But a lot of times some people see things blurred, not because of the eye problems, but the brain's visual cortex has a problem. The visual system is so complex that many parts are likely to go wrong.

11. Eyes can adapt to the blind spot

Some eye problems may lead to visual blind spots. And these blind spots can be significantly weakened or disappeared by the adaptation of the brain and eyes, just as the brain can adapt to the inverted image. The brain allows the healthy eye to fill in these blind spots.

12. The dry your eyes, the more you cry

The three main components of tears are fat, mucus and water. When these three ingredients do not reach the due amount, our eyes will feel dry. The brain then produces more tears in response.

13. The eyes repair very quickly

With proper care, the eye can repair a scratch on the cornea within 48 hours.

14. The newborn has no tears

Newborn babies don't shed tears, even if they cry loudly. Infants will only begin to shed tears at 4 to 13 weeks of age.

15 Iris heterochromia, like the Persian cat

Some people have two eyes born in different colors. This condition is known as iris heterochromia.

16. Eye muscles are very busy

Of all the muscles in the human body, those muscles that control the eye are the most active.

17. Working parts

The human eye consists of two million working parts. They make your eyes have a perfect function.

18. Shark eyes

The shark cornea is very close to the human cornea. Because of this similarity, shark corneas are often used in human corneal transplants.
