eyes - palpebral aperture position
Evaluated separately for the left and the right eye in the frontal view. A ruler or a protractor can be used to determine the category. The palpebral aperture position is determined in accordance with the angle formed by the connecting line of the inner and the outer corner of the eye and the median plane. This trait has three categories: 1. the outer corner is lower (the angle is lower than 90°), 2. straight (a right angle), 3. the inner corner is higher (the angle is larger than 90°).
