Almond-shaped eyes are a physical characteristic that has been used to describe Asian people in literature and media. However, this description has been criticized for perpetuating stereotypes and marking non-white characters as "others". There are no specific ingredients or materials associated with almond-shaped eyes. However, cosmetics have been used historically to define the eyes in the iconic almond shape seen in masks and sculptures, with kohl made from burnt almonds, oxidized copper, copper ores, lead, ash, and ochre being used for this purpose. Contact lens materials are also used to fit the eye and improve vision, but there is no specific mention of almond-shaped eyes in the context of contact lenses.
