1, why is the eyelid still "cracked"
Eyelids should be called eyelids medically. They are two movable eyelids, which are located in front of the eyeball and constitute a barrier to protect the eyeball. So as to protect the easily injured eyeball and its outermost cornea, and has the function of spreading tears to the whole conjunctiva and cornea.
When some people's upper eyelids open their eyes, there will be a very obvious gully, which is what we call double eyelids; But there are still some people who don't have this kind of gully on their eyelids, and the whole upper eyelid is smooth. This situation is called single eyelid.
Generally speaking, whether the eyelid is a single eyelid or a double eyelid has a great relationship with the structure of the upper eyelid. Among them, two small muscles on the eyelid play a key role: orbicularis oculi muscle and levator palpebrae.
Simply put, the orbicularis oculi muscle is responsible for closing eyes and grows around the whole eye. The "eyelid jump" we often say is the twitching of orbicularis oculi muscle caused by abnormal nerve excitement; The levator palpebrae superioris muscle is the muscle responsible for opening eyes, which is connected with the tarsal plate on the eyelid. If this muscle atrophy, people's vision will be greatly affected.
If a person's upper eyelid skin and subcutaneous fat are thin, and the orbicularis oculi and levator palpebrae are well developed, when they open their eyes, the orbicularis oculi and levator palpebrae will move together, which will form wrinkles on the upper eyelid. These are double eyelids.
However, if a person's upper eyelid skin and subcutaneous fat are thick, and the orbicularis oculi muscle is developed but the levator palpebralis muscle is not developed, then the orbicularis oculi muscle is moving in the process of opening eyes, and the levator palpebralis muscle can't move the meibomian on the eyelid and the surrounding skin, then the eyelid will not form wrinkles and become a single eyelid.
Why do some people have double eyelids and some people have single eyelids?
Single eyelid or double eyelid is fundamentally determined by genes. Eyelids are dominant genes, while single eyelids are recessive genes.
For a simple example, if the genes controlling single eyelid and double eyelid are big A and small A respectively, then the combination of aa and Aa is double eyelid, and AA is single eyelid. According to this ratio, the ratio of double eyelids to single eyelids should be 3: 1. So according to the genetic formula, you can also roughly calculate what kind of eyelids your child may be in the future:
Aa (double eyelid) +Aa (double eyelid) =Aa (double eyelid), Aa (double eyelid), Aa (single eyelid) -2/3 children have double eyelids, 1/3 children have single eyelids.
Aa (double eyelid) +Aa (double eyelid) =Aa (double eyelid), AA (double eyelid)-child 100% double eyelid.
AA (double eyelid) +AA (double eyelid) =AA (double eyelid)-child 100% double eyelid.
Aa (single eyelid) +aa (single eyelid) =aa (single eyelid)-the child is 100% single eyelid.
Aa (single eyelid) +aa (single eyelid) =Aa (double eyelid), Aa (single eyelid)-The possibility of children having double eyelids is 1/2, and the possibility of having single eyelids is 1/2.
AA (double eyelid) +aa (single eyelid) =Aa (double eyelid)-child 100% double eyelid.
So statistically speaking, people with single eyelids are much less than those with double eyelids.
There is a saying that the inner double eyelid is a single eyelid, but from the genetic point of view, the so-called inner double eyelid is essentially a double eyelid ~ just not so conspicuous ~
Others have only one pair of eyes. Such "rare animals" are very rare.
Why do double eyelids become single eyelids when sleeping?
Generally speaking, single eyelid and double eyelid are genetically determined, and the possibility of trait change is very small.
In some special cases, double eyelids may look like single eyelids.
If you drink plenty of water before going to bed, or sleep for too long, sleep in an incorrect position, etc. There is edema in the upper eyelid of human body, which will not disappear for a while, which will make the folds of double eyelids disappear. The original double eyelid looks exactly the same as the single eyelid.
If you have symptoms of eyelid edema and double eyelids become single eyelids, you don't need to worry. When the edema disappears, the eyelid folds will reappear and the double eyelids will come back!
If the edema persists, try rolling hot eggs around your eyes to quickly reduce the swelling. Some eye creams have a lifting and firming effect, which can make the eyelids swell faster. On this basis, you can also gently massage around your eyes through some methods to promote blood circulation and make your eyelids swell faster.
If the eye edema does not subside for a long time, you may need to go to the hospital to see if there is eye disease. Don't let this affect your eyesight.
Double eyelids are justice? Does a single eyelid look good?
From people's aesthetic point of view, double eyelids look better than single eyelids ~ this is also scientifically explained.
From an aesthetic point of view, single eyelids often give people the impression that their eyes are small and "not beautiful", and they are not as expressive, emotional and bright as double eyelids.
Therefore, more and more people choose to do plastic surgery and use double eyelid stickers for the sake of good eyes. Blinking online can be changed from single eyelid to double eyelid, and the principle and scientific basis are not elegant. Don't try blindly ~
More interestingly, in ancient China, a single eyelid was a beautiful woman: all the beautiful women in the pictures of ladies in past dynasties were single eyelids without exception. The aesthetics of all dynasties are not unchangeable, such as the Tang people who advocate _ Yan and fat, and the Ming and Qing people who advocate thinness and softness, but the only constant is the preference for single eyelids. In painting, from the oldest existing figure painting ── A Historical Picture of Women by Gu Kaizhi in the Eastern Jin Dynasty to the late Qing Dynasty and the early Republic of China, and even before the Anti-Japanese War, the preference for single eyelid has never changed.
Westerners rarely have single eyelids, and whites almost all have double eyelids. Therefore, some people think that in the early genes of China people, single eyelid is the majority, and due to population migration, intermarriage and other reasons, foreign genes with double eyelids have gradually occupied the mainstream.
So, if a sister or a man with a single eyelid says that he is a real traditional oriental beauty, don't refute it, maybe he is telling the truth ~
