• #9-1. Differences in attractive eyes across races and ethnicities II


    2. Anthropometric study on average and attractive eyes among different races or ethnicities  


    I would like to discuss photogrammetric and anthropometric characteristics of the different configuration of eyes in average and attractive faces of different races.


    How can we define attractive eyes? Many studies have provided anthropometric or photogrammetric data, however, few has invested the actual or scientific photogrammetric differences between attractive eyes and average eyes in different races and ethnicities. In my previous study, I had reported that attractive facial configuration or shapes were much different according to racial or ethnic background.1,2


    Subsequently, I have also published an original article on the journal ‘Aesthetic Plastic Surgery’ about the photogrammetric research findings relating different peoples’ perception on attractive eyes, which reported photogrammetric details of average eyes and attractive eyes in terms of racial differences.3

    In this study, I created average  composite faces by face-morphing methods 4-6 by using my previous facial prototypic images of attractive faces in different races. The composite  faces obtained in this way included Average Korean Face (AVK), Attractive Korean Face (ATK), Attractive Asian Face (ATA), Average Caucasian Face (AVC), Attractive Caucasian Face (ATC), Average Black face (AVB), and Attractive Black Face (ATB) (Image 1).


    I examined and analyzed the mathematical characteristics of average and attractive eyes that differ between races by assessing the relative balance, size, or harmony of individual eyes after standardizing each racial interpupillary distances as reference values. We will take a closer look at  my research results in this article.

    When performing blepharoplasty, I am afraid that aesthetic plastic surgeons often overlook something critical; Many oculoplastic surgeons often neglect to measure the absolute and relative distance between tow centers of each eye. The distance usually called as ‘interpupillary distance’. I want to address the importance of measuring the distances not only comparing the distance with facial width from the patient but in comparison of average values of their own racial peoples.


    Measuring the ratio of the pupillary distance to the facial width in different races/ethnicities can show  relative distance of two pupils in relation to the facial width. This is called the “set of eyes.” There are different sets of eyes. It includes average set eyes, wide set eyes, or close-set eyes. The below Image 2 shows my measurements obtained from dividing the pupillary distance by the  faccial width. Lower numbers indicate closer set of eyes and higher numbers indicate wider set of eyes.
