Is single eyelid a physiological defect?

There is an aesthetic difference between double eyelids and single eyelids, and morphological and anatomical differences between the two in the perception of plastic surgeons.

But from an aesthetic point of view, single eyelids tend to give the impression that the eyes are small and "less beautiful". There is no more emotional expression like double eyelids.

From a morphological point of view, the difference between single eyelid and double eyelid, except that there is no difference in the transverse fold at the upper eyelid, the entire upper eyelid of the single eyelid is thicker and appears more bloated, **slightly drooping, and when looking at eye level, the root of the eyelashes is covered and appears shorter; As the saying goes, long eyelashes are like a beautiful curtain, and the upper eyelids of double eyelids are thinner, and the eyelashes appear longer, giving people a clearer feeling.

There are also significant differences between the two in terms of anatomy. The single eyelid is thicker, the subcutaneous tissue is higher, the orbicularis oculi muscle is more developed, the fat behind the orbicularis oculi muscle is more, the meisal plate is thin and narrow, and the muscles that open the eye, the levator palpebrae superioris muscle, are underdeveloped, so they appear bloated; The opposite is true for those with double blepharoplasty. Based on the anatomical structure, when the single eyelid is opened, the ** in front of the tarsal plate and the orbicularis oculi muscle cannot be lifted together with the tarsal plate, so the upper eyelid cannot form a fold and manifest as a single eyelid.

When the eyes are opened, the ** and orbicularis oculi muscles below the tarsal line in front of the tarsal plate can be lifted together with the tarsal plate, so the upper eyelid appears wrinkled, which is manifested as double eyelids.

Not really. Our biology teacher once said that a single eyelid is an evolutionary form.

It is said that single eyelids are produced by genetic mutations, not many (most of them are double), so people with single eyelids evolved after double eyelids.

So once the single eyelid boy was very popular

No, it's an individual difference, it's like someone whose tongue can be rolled into a 0 shape, and someone can't, in addition, someone's single eyelid is an inner double, that is, the double is too strong, and it can only be seen when the eye is on the wall.

Single eyelids have the advantages of single eyelids, and double eyelids have the beauty of double eyelids. It's all good to pull.

Flawed by your size, that's called Danfeng Eye.

I've lived for so long, what does it matter if I don't like it, just open a double.

If a single eyelid is a defect, then what is a "triple eyelid"?

Answer: The substances in the nucleus that are easy to be dyed dark by basic dyes are called chromosomes, chromosomes are composed of DNA and proteins, and the fragments of DNA with genetic effects are called genes, and genes determine the traits of organisms

Answer: The traits of organisms are controlled by genes Traits refer to the morphological characteristics, physiological characteristics, aging and behavior patterns of organisms; The single and double of human eyelids are the morphological characteristics of people, which are traits and are determined by genes

Therefore, point A dismantles the forest and upgrades: The traits of organisms are controlled by genes
