oneeyed

One-eyed is an adjective and sometimes a noun used to describe a person, animal, or thing that has only one functioning eye or lacks vision in one eye. In medical and everyday language, it is commonly used to refer to monocular vision or to imply blindness in one eye, whether due to injury, disease, or congenital conditions. The term can also describe objects or creatures with a single visible eye or reduced depth perception when viewed from one side.

In humans and animals, one-eyed conditions encompass a range of situations, from accidental loss of an eye to congenital absence or deformity. The concept is often used descriptively in anatomy, ophthalmology, and zoology, and it appears in discussions of vision, spatial awareness, and behavior influenced by monocular sight.

In popular culture and symbolism, one-eyed imagery frequently connotes partial Perception, bias, or a narrowed viewpoint. The term appears in folklore and fiction to describe beings such as cyclopes or characters whose perspective is limited to a single eye. In card games, “one-eyed” refers to the Jack of Hearts and the Jack of Spades, which are depicted in profile with only one eye visible; these cards can carry special status in certain games or stories.

Notable uses include the pirate character “One-Eyed Willy” from the 1985 film The Goonies, whose legend centers on hidden treasure. The expression also appears in idioms and titles, often as a metaphor for partial vision or a particular point of view. See also monocular, cyclops, one-eyed jack.
