This character doesn't have normal human eyes; for any of various reasons his eyes are like those of an animal. He may have slit cat eyes, compound insect eyes, glossy and bulging fish eyes or piercing bird's eyes, among a menagerie of possibilities.

These eyes may be just for show, a mere cosmetic difference brought about through a PartialTransformation, genetic alterations or a spell. Frequently, and especially for bird's eyes, they carry SuperSenses related to sight.

The BeastMan and some {{Kemonomimi}} will have eyes matching their particular choice of animal. In SciFi settings, characters who are HumanAliens (including some RubberForeheadAliens) may also have unusual eyes. In these two cases, this is to [[ShowDontTell silently remind the audience]] that the character in question is [[HumanAliens not actually human]].

See also HellishPupils, which may be shaped like those of a cat, goat or reptile. See also SupernaturalGoldEyes, when golden eyes show a supernatural connection. Not to be confused with FishEyes, PuppyDogEyes or AnimalEyeSpy. The inverse of this would be CartoonyEyes, in which animals have eyes that are human-like (although very exaggerated or simplified).
