Abstract
The purpose of this study is to clarify the relationship between an attractive smile and eye shape. Seven images of attractive eyes and seven images of unattractive eyes were selected from 120 smile eye images as experimental samples. Panel traced outlines of eyes in images, and the number of characteristics in the optic fissure surrounded were calculated. The characteristics associated with attractive eyes and unattractive eyes in smiles were then compared. As a result, significant differences (p<0.01) were confirmed in the area, circle degree, vertically length, maximum segment vertically intersected with the maximum length, surrounding length and needle shape degree. Common characteristics of optic fissure that were considered to be attractive were smaller area, smaller circle degree, shorter vertical length, shorter surrounding length, and larger needle shape degree. We discovered that eyes with a narrow optic fissure were considered to be the most attractive.
