Single eyelids vs. double eyelids: What's the difference? How many layers are there in hooded eyes?

There is a noticeable difference between single eyelids and double eyelids at first glance. Single eyelids are more common in Asians, especially in men, who have a higher proportion of single eyelids than women. Some people may have hidden single eyelids that make their eyes appear smaller, while others may have one single eyelid and one double eyelid, making their face look asymmetrical. Nowadays, many people choose to have surgery to transform single eyelids into double eyelids to make their eyes appear brighter and more vibrant. But before making a decision, let's understand what single eyelids are first.

What are single eyelids? What do they look like?

Single eyelids are a condition where the eyelid lacks a crease when the eyes are open. This is because the eyelid muscle is not attached to the skin, so when viewed from the front, the eyelid appears smooth and flat, without the crease found in double eyelids. This condition is common in Asians, especially in East Asian countries such as China, Japan, and Korea. Single eyelids are not considered an abnormality, but rather a genetic trait passed down through generations. Some people may find that they make the eyes look small or that they look sleepy all the time.

Are single eyelids and hidden double eyelids the same?

Although they may look similar, single eyelids and hidden double eyelids are different. Single eyelids have no eyelid crease at all, while hidden double eyelids have a crease, but it is hidden under the tissue or fat, making it less visible. Some people may only see the crease when their eyes are wide open. This difference affects the choice of correction method. For example, people with hidden double eyelids may be able to correct them by surgically removing the fat. But people with monolids may need to have a double eyelid created.

What causes monolids?

Single eyelids are caused by three main factors: genetics, eyelid muscle structure, and the amount of fat around the eyes. Most often, it results from genetics causing the eyelid muscle not to attach to the eyelid skin, or attaching too low. In addition, excessive fat around the eyelids can also cause single eyelids. In some cases, it may be due to weakened or sagging eyelid muscles with age.

What are the common problems in people with single eyelids?

Single eyelids can lead to various physical and psychological problems. Let's look at some of the common problems in people with single eyelids. And how does it affect daily life?

Vision

Having monolids can affect vision in some cases, especially when accompanied by ptosis (drooping eyelids), causing the upper eyelid to cover too much of the eyeball. This results in inability to fully open the eyes and a narrower visual field. Some people have to constantly raise their eyebrows to see clearly, which can cause headaches and fatigue in the forehead muscles. In the long term, it may affect the efficiency of daily vision use.

Eyebrow irritation

Ingrown eyelashes are another common problem in people with monolids. This is because the direction of eyelash growth may be abnormal, causing the eyelashes to curl inward and irritate the cornea. This can lead to irritation, burning, watery eyes, redness, and in severe cases, corneal infection. If left untreated, it can affect vision in the long term.

Loss of Confidence

Monolid eyes can affect self-confidence, making the eyes appear small, droopy, or sleepy all the time. Some people feel their face looks dull, especially in photos or when meeting people, leading them to constantly raise their eyebrows or open their eyes wide. Besides causing fatigue, this can also affect overall personality and social interactions.

SolutionsMonolid Eyes

For those who want to correct monolids, there are several options, both temporary and permanent. Each method has different advantages and limitations. We should consider choosing a method that suits our eye condition and needs.

Double Eyelid Stickers

Double eyelid stickers are a popular temporary solution because they are easy, inexpensive, and non-surgical. The stickers create a crease in the eyelid, resulting in a temporary double eyelid. However, this method has limitations: they must be used daily, which may irritate the eyelid skin or cause an allergic reaction to the adhesive. The resulting double eyelid may also not look natural, especially if the stickers are of poor quality or applied incorrectly. Furthermore, long-term use may lead to eyelid muscle weakness.

Double Eyelid Surgery

Double eyelid surgery is a permanent solution. A surgeon creates a double eyelid through surgery. Several techniques are available depending on individual needs, such as suturing, skin excision, or fat manipulation. This method provides permanent and natural results, but costs, recovery time, and surgical risks must be considered. Consult a specialist surgeon to choose the technique best suited to your eye condition.

Can I get double eyelids on only one eye?

If you have a single eyelid on only one side, it is possible to have surgery to create a double eyelid. However, this requires specialized expertise from the surgeon, as they must create a new eyelid that complements the existing eyelid on the other side in terms of height, depth, and shape, ensuring both eyes are balanced and look as natural as possible. This type of surgery requires careful planning and measurement.

In summary, single eyelids are a common genetic trait in Asians. While not an abnormality, they can affect vision and self-confidence. Currently, there are many solutions to choose from. You can choose a clinic and consult with the expert doctors at Sky Clinic, who specialize in double eyelid surgery, inner corner eyelid surgery, correction of ptosis (weak eyelid muscles), concealed scars under the eyebrow, and removal of under-eye fat bags, to receive treatment that is appropriate for your problem.
