I can consciously defocus my eyes, by changing the size of the pupils, it's very hard to notice even when I show people and tell them to look closely, but it's great for intimidating assholes who are really close up, I also don't know what colour my eyes are, as they have been described as blue, green or brown once even yellow depending on the light, for the most part they are green, also when really pissed off sometimes a gray colour spreads across them I've actually watched it happen.

One of my ex-classmates has eyes like that. (I think he was called cat eyes in middle school.) Sadly he doesn't see better in twilight, but prefers shades in bright daylight. I hear he wants to be a bank CEO...

This troper has a friend who has eyes like these, but she subverts the trope because she's one of the nicest people he knows.

This troper's right eye, he is told, changes colors among various shades of blue and grey when he is emotional, or in a certain light, though he's never personally seen it. (The left eye, however, is blind-from-birth, and is always the same neutral milk-white.)

That belongs under KaleidoscopeEyes, doesn't it?

In real life, small cats, goats and sheep have eyes like these. (Big cats like lions and tigers do not, however; they have round pupils like humans.)

Squid eyes are pretty cool... W-shaped pupils. They see in a slightly different way than we do, of course, being able to see light polarization.

Horses, too. It's hard to see this on the typical dark-brown horse eye, but easier to see on blue eyes like this one.

Kind of hard to see because of the TechnicolourEyes though, wow the inner ring is a really dark blue.

This troper shat bricks upon seeing that image.

This troper instantly came up with a dozen good ideas to make her angel characters creepier.

This troper finds the eyes of both horses and goats to be indescribably cool.

I once had a teacher in elementary school who had a smaller, second pupil conjoined to the first in at least one of her eyes. That's the only thing I remember about her.

Apparently, when I scream, my pupils go into slits.

Wow! That would be both scary and awesome to see, especially if you were facing me.

Are you Rena?

My brother has eyes that look kinda cat-like, sometimes he gives me the creeps when he looks at me like that. Not to mention it's especially intimidating when he does the Clint Eastwood stare.

This One's eyes change color and shape. Going from Hazel to green, once to black (likely the pupils swelled up so it just looked like it...maybe). The Irises have also gone slited like a cat and hourglass shaped like a goats, Several of my friends have seen it. Interesting note: there are old tales of non human ancestry in this one's family.

Well it would explain the eye thing. Maybe. It depends what kind of non-human it was.

I am having trouble refraining from making an offensive joke here.

The Sídhe, mostly, we're an old Scottish family(I'm 2nd gen American). I've also talked with a distant relative who said demons were also in the family tree.

Strangely, that's actually pretty cool. Even if it's not true, the legend itself is rather neat.

If the eyes are a family trait, they're probably the source of the story.

You screw one goat, your descendants never live it down....

Variation, I have an unusual eye condition that causes me to be sensitive to any form of light (but especially UV). My eyes themselves look like normal blue eyes but the only way I can live a normal(ish) life is to wear tinted contact lenses originally designed for sportswear. This means that I end up with black eyes, with the pupil indistinguishable from the iris. I've been told it can be quite unnerving

I don't have hellish pupils, per say, but I do have blue eyes that seem to change based on my mood. Normally, they are darkish blue around the edges of the iris with spikes of ice blue going out, but when I get mad apparently my eyes become extremely cold looking, pale, and emotionless. TranquilFury indeed.

I have deep-set brown eyes with gold-amber flecks, and aside from being told that my eyes are very beautiful I have also been told that my eyes get darker when I'm angry. I've also heard people say that my eyes have a golden cast to them in a certain light.

A girl I met once actually had Raistlin-style hourglass-shaped pupils.

You must introduce me to her.....NOW!

This Troper has eyes that are the right shape and the irises are shades from blue to green (depends on the color of what he is wearing) but the area around the pupil is a dark yellow. Probably doesn't help that this troper constantly gives off an unintentional DeathGlare.

A character in a collaboration fic this troper is working on is called Dr. Ambientus, he has red eyes...but the pupil is divided into hypnotic red rings. He is also pure and simple HighOctaneNightmareFuel, he dances with a female corpse, offers to neuter a dog without anesthetics and eats a little girl's heart before every dinner...just because he can.

This anonymous Troper's best friend has greyish-blue eyes that change color with the light and her moods. At one point when she was really pissed off they were ''mossy green''.

You'd be looking for this trope, then.

This troper's pupils contract slightly when angry. Combining it with a KubrickStare tends to freak people out.

This troper has a character with only pupils. No irises, just the whites and the pupil.

are you me? Mine is a changeling: the dreaming character.

This troper has been told on many occasions that her eyes look catty if you don't look too closely.

This troper's pupils, while able to change size, are almost always stuck at maximum dilation, and have been that way ever since having deadly-nightshade eye-drops to open them up in the months leading up to his eye surgery, age five.

This troper has both seen others and been working on biofeedback exercises that let you partially dilate your pupils at will, letting you make all sorts of cool shapes. Well, slit like, anyway. It's also ridiculously hard to do, and even harder to hold for more than a few seconds. Still cool though.

This troper has eyes that can move independently from each other- great for reading while keeping an eye on siblings.

Does it count if the eyes are perfectly ordinary, only red? Very red?

Wrong trope

Kulture here, I have odd blue eyes with a small ring of green immediately next to the pupil that filters out into the rest of the iris like veins. The effect is that with my large pupils and general demeanor I've managed to give people (myself included) vertigo with them.

This one girl at this troper's high school has eyes like that. It's almost like someone's taken all but the outside ring of her iris out. Admittedly, after a completely earth-shattering realization I had, I realize it probably has something to do with frequent (ab)use of marijuana. But she does look—and act—like some sort of succubus. God, those eyes...

When this troper was born, her irises were dark blue, the whites of her eyes were pale blue, and her pupils...were square. According to her mother, sometimes her (now round) pupils will start to show slight points again.

Apparently my eyes are so dark that you can't see the pupil from an arm's length away. It will show up on a sunny day, because my eyes light up and become ridged brown with a clearly visible pupil. But on cloudy days and when I feel extreme emotion, apparently you can't see my pupils and I look like I'm from hell. I'm innocent, really!

This troper's pupils aren't oddly shaped, they're just ''enormous'', constantly, never contracting like they're supposed to. It's genetic; her sister has it too. It's quite noticeable as this troper's irises are a pale green, and she is fairly frequently assumed to be stoned. She's never touched anything of that sort in her life. Fun fact, though-- her huge pupils mean she has to wear sunglasses most of the time like Crowley.

I can't be the only Troper who wants to invoke this trope with contact lenses. They're so coool!

At least twice (once when he was really sick and once when he was dehydrated) this troper's eyes have turned almost completely black.
