Canthus
Either corner of the eye, where the upper and lower eyelids meet.
Also: canthi, eye corner
Each eye has two canthi: the inner (medial) canthus beside the nose and the outer (lateral) canthus towards the temple. The line joining them sets the eye's tilt. The inner corner holds the small pink caruncle and is the point an epicanthic fold may cover. Makeup artists talk of the inner corner when placing highlight, and of the outer corner when drawing a wing of liner or kajal.
