Hey guy, thanks for watching the Chen Dynasty. It's Mike Chen.
There is, of course, beauty in diversity.
And just talking about Asians here. For one, the distinctiveness of the physical features among Asian people partly contribute
to their overall identity and what makes each and every one of them unique.
Their eyelids in particular are admittedly one of their physical attributes that make
them stand out.
And though there are some people who hold the stereotypical notion that all Asian eye, somehow all look
the same, nothing is further from the truth In reality, the eyelids have a variety of
unique characteristics in every individual of Asian descent.
So let's talk about the asian eyes.
There are many differnet types of asian eyelids and
when we say "Asian," we are referring to the varied eyelid morphologies currently
present in the continent of Asia, and this includes a variety of races like Chinese,
Korean, Indian, Middle Eastern, Southeast Asian and more.
However, most of the published literature about the Asian eyelid are focused more on the
morphology of eyelids that are common among those of Chinese descent.
And so while we will be covering as many types of asian eyes
from different regions of the continent as possible,
a large portion of this video will be tackling eyelid morphology of asians whose
origins can be traced back to the continents far eastern regions
So what are some of the unique characteristics of asian eyes or eyelids?
The design and distinctiveness of different types of eyes is primarily the result of people's
genetics.
There are many factors at play in the beginning and over the course of your life that will
contribute to the determination of what type of eyes you are born with, and how they will
develop as time goes by.
The structure of your face and the eye area, including minute considerations like the level
of the skull and the shape of your orbital rims, are just some of the elements that determine
the angle and width of your eyelids.
For many Asians, the unique characteristics of the upper eyelids are what primarily sets
them apart from other races as well as from each other.
For example, their upper eyelid crease is not as apparent compared to the crease of
a Caucasian eye.
The typical Caucasian eyelid is referred to as semi-lunar and has a prominent crease.
However, among Asians, they could have a pair of eyelids without a crease, eyelids with
non-continuous or broken crease, eyelids with a complete crease, and even eyelids with multiple creases.
Or a freak like me with one eye with multiple creases and the other one with two creases...it's all messed up.
Anyway just like in Caucasians, the eyelid skin is also the thinnest skin in the body of Asians,
and the thinnest part of that area is found near the ciliary margin of the eye, which
has a thickness of 0.3 mm.
Then, the upper eyelid skin gradually thickens as it gets closer to the eyebrow, and just
below this area, the skin's thickness is around 1 to 1.3 mm.
It is important to note, however, that the Asian upper eyelid is generally thicker than
that of Caucasians.
And so, the difference in skin thickness between the supratarsal area and the area nearer to
the brow are typically more visible and obvious among Asians.
The Asian upper eyelids also look puffier and have more fullness to them.
This is because there are four fat pads found in the Asian eyelid. These are the subcutaneous, pretarsal,
submuscular, and orbital fat pads.
Subcutaneous, pretarsal, and submuscular fat deposits, in particular, are more prominent
in Asians and explain the eyelids' puffy appearance.
Fat pads are also thought to be one of the factors that contribute to the formation of
single eyelids.
Now let's talk about the epicanthal fold in asians.
Among people of Asian descent, the nose bridge does not elevate as it does in other ethnicities.
Because of this, the epicanthal fold is a prominent feature that is common among Asians.
But what is the epicanthal fold?
Well, it is a semilunar flap of skin that descends along the side of the
nose from the upper eyelid to the medial aspect of the lower eyelid.
It can also cover the medial canthus or the inner corner of the eye.
There are a variety of factors that influence whether someone develops epicanthic folds or not.
Aside from age and certain medical conditions, its appearance in the features of the eyelids
is largely dependent on geographical ancestry.
The epicanthal fold is common in people of many, though not all, groups of East Asian
as well as Southeast Asian descent.
It is also found in some members of Native Americans, Central Asians, Tibetans, in some
parts of Africa and more.
The epicanthal fold is believed to have evolved as a defense against extreme cold temperature
and extreme light that regularly occur in Eurasian arctic and northern regions.
They also serve to protect the eyes against dust in regions with large areas of deserts
such as in northern China, Mongolia and in several parts of Africa.
The epicanthal fold is distinct from the upper eyelid crease, and the combination of the
presence or absence of these features, and the way they are formed in our eyelids are
some of the ways we can identify the different types of Asian eyes that exist today.
So now let's talk about the different types of eyelids.
The upper eyelid crease can be divided into three types.
The first one is referred to as the single eyelid or monolid, in which there is no visible
lid crease below the brow area.
There is also such a thing as a low eyelid crease and they can be low-seated, nasally
tapered and can include a hidden fold.
The last type is the double eyelid, which is essentially identified by its well-formed
supratarsal crease.
Monolids or single eyelids can be classified further into several subtypes: puffy, sunken,
flat, partial and hooded.
Because of the fat deposits on the eyelids, monolids can appear like they're puffy,
this puffiness is what makes the eyes look half-closed in some Asians.
However, it is also possible to have minimal fat deposit on a monolid – as is the case
in the sunken subtype.
With sunken monolids, people can have a bigger-looking or smaller-looking set of eyes, and the eyeballs
appear more clearly.
Sunken monolids also resemble deep-set eyes, minus the eye creases.
Monolids can also be neither sunken or puffy, and these eyelids are referred to as flat
monolids.
There are also such things as partial monolids or demi monolids, which are almost the same
as double eyelids.
The only difference is that this subtype only shows half or a part of what double eyelids
look like.
This type of monolids also has creases but in this case, the lids lack enough muscles
to pull these creases into forming full double eyelids.
Lastly, the fifth subtype of monolids – the hooded monolids – is characterized by its
hidden creases.
However, due to lid thickness, which is caused by an extra layer of skin drooping over, these
creases usually cannot be seen.
This makes the eyes appear smaller and sometimes, even sleepier.
While this trait usually runs in the family, it can also be brought about by aging as the
skin of the eyelids begins to droop over time.
The double eyelids can also be divided further into several subtypes: the infold double eyelid,
the inout-fold double eyelid and the outfold double eyelid.
In the infold double eyelids, the height of the upper lid crease is lower than the epicanthal
fold.
The medial eyelid crease is also hidden by the coverage of the epicanthal fold, which
makes the eyelids look thin, only to become more noticeable in the mid-lateral area of
the lids.
The inout-fold double eyelid is the middle form between the infold and the outfold subtypes.
The crease starts from the tip of the corner of the eye and gradually extends to the other
end of the eye.
The crease converges and tapers nasally to the eyelid margin.
The height of the crease is usually small or medial, and is usually located right on
the epicanthal fold.
And lastly, the outfold subtype, the height of the crease of the double eyelid is higher
than the epicanthal fold.
This particular eyelid crease starts apart from the medial canthus without touching the
inner corner of the eye.
It is also possible to have an outfold type of double eyelids that is without epicanthal
folds.
Of course, the examples we have mentioned here are not the only types of Asian eyes
that are in existence today.
There are also Asian eyes with parallel creases, and even rarer, Asian eyelids with a reversal
epicanthal fold.
As we become more of a global society, genetic diversity continues to break the barriers
of what Asian eyes are expected to look like.
And so, future generations may have even more varied and unique eye characteristics than
what we have today.
I wanted to make this video because I grew up and I knew a lot of other asians
grew up in a similar environment where the people around us was not primarily asian
And I got made fun of with the kungfu noises and, of course, the
whole eye thing.
And comments of " Oh Mike Mike how come all asian eyes are slanted?"
So hopefully this video can educate and also let people know that, hey nope, not all asian have the same type of eyes.
But I do hope we get to the point that stereotypical labels of people's appearance
become a rare and unusual practice and not the observed norm.
After all, there is truth a lot of truth in the saying that there is always more to everyone than meets the eye.
All right guys, thank you all so much for watching this video. I'll see you later.
