Every single eyelid girl has had the idea of becoming double eyelids, right? Because girls know that the difference between having double eyelids and not having double eyelids is really big. Of course, now we all know that you can easily become double eyelids through surgery. But what girls need to know is how to make a pair of double eyelids that suits them. The doctor will analyze the following aspects: the length of the eyes The length of the eyes is an important factor in the outcome of the surgery, the longer the eyes, the more natural the result. People with short eyes who want to have the effect they deserve can open the inner and outer canthus at the same time as the blepharoplasty, which will result in more beautiful eyes. Eye Convexity Using the brow bone as a reference, eye convexity can be classified as sunken, flush or bulging. Most Asian eyes are flush, and such eyes are not suitable for making the double eyelids too wide to avoid leaving an unrealistic feeling. In the case of congenital or long term eyeglass bulging, blepharoplasty is not suitable and the results may not be very good due to the bulging eyeballs. According to the “three chambers and five eyes” principle, a standard face width should be the length of five eyes, and the distance between the two eyes should be equal to the length of one eye. If the distance between the eyes is too wide, the person will look dull and unnatural; if the distance between the eyes is too narrow, the person will look constricted. The condition of the skin under the eyes also has an impact on the outcome of the surgery. If the eye skin is elastic and the eye fat is small, the post-operative recovery will be fast and the effect will be natural; if there is excess fat on the eyelids, it should be removed at the same time as the surgery, otherwise the eyelids will look thick and unnatural; if there is significant laxity in the eyelids, it will make the surgery more difficult and the double eyelids made will be affected by the skin folds, making it difficult to achieve the desired effect. Coordination of facial features The coordination of facial features refers to the ratio of “three chambers and five eyes”, which is the general standard ratio of the length and width of a person’s face, and if it does not conform to this ratio, it will be distant from the ideal face shape. Nowadays, there is a more precise standard based on the “three chambers and five eyes”, and each part is considered beautiful if it meets this standard, as follows: the width of the eyes should be 3/10 of the width of the face at the same level; the length of the chin should be 1/5 of the length of the face; the distance from the center of the eyes to the bottom of the eyebrows should be 1/10 of the length of the face The surface area of the nose should be less than 5/100 of the total area of the face; the ideal width of the mouth should be 1/2 of the width of the face at the same level. Overall, there are two major points in total that affect how the post-operative effect of double eyelid surgery is affected by personal factors: first, the age of the candidate, the convexity of the eyes, the distance between the two eyes, the coordination of the five features, and the condition of the eye skin. Secondly, whether the post-operative care of double eyelid is in place, which is also very crucial. In fact, in addition to these two major points, whether the double eyelid looks good or not depends on the level of skill of the doctor. If you are not good, even if you have good eye conditions, the double eyelid cut out is not good. First of all, the pre-operative design of the double eyelid is very critical, taking into account the eye conditions of the candidate, including the above-mentioned eye length, the spacing between the eyes, the height of the brow bone, the eye skin and so on.
