Eye shape refers to the outline and structure of the eyes, which can vary significantly among individuals. Common shapes include almond, round, and hooded. Almond-shaped eyes are slightly pointed at the ends, while round eyes are wider and more circular. Hooded eyes have a fold of skin that partially covers the eyelid, giving them a unique appearance. The shape of the eyes can influence how makeup is applied and can affect the overall look of a person's face. Additionally, certain eye shapes may be more common in specific ethnic groups, contributing to the diversity of human features across different populations.
