You’ve probably seen it a thousand times without really thinking about it. A character onscreen has eyes that don't quite line up. Maybe one drifts toward the ear while the other stays fixed on the hero. Or perhaps both pupils seem to be doing their own thing entirely. In the world of animation, we often call this a "lazy eye," though the medical term is actually strabismus or amblyopia.
It’s weirdly common.
For years, animators used misaligned eyes as a shorthand for "this person is wacky" or "this creature isn't very bright." It was a visual gag. A punchline. But things are changing. Lately, lazy eye cartoon characters have transitioned from being the butt of the joke to being genuine fan favorites who represent a huge portion of the population that deals with vision issues. Honestly, seeing yourself—or your kid—reflected in a Saturday morning cartoon can be a bigger deal than most people realize.
The Most Famous Faces of Strabismus in Animation
Let's talk about Derpy Hooves. If you were online at all during the 2010s, you know the drama. This My Little Pony: Friendship is Magic background character was born from a literal animation error in the very first episode. One eye was looking up; the other was looking down. Fans went wild. They named her, gave her a personality (she loves muffins), and turned her into an icon.
But then things got complicated.
When the creators officially leaned into the "lazy eye" look and gave her a clumsy voice, a massive debate erupted. Was it an insult to people with disabilities? Or was it a win for representation? Eventually, they softened her design and changed her name to Muffins in some credits, but the legacy of Derpy remains. She’s perhaps the most famous example of how a "glitch" became a symbol for an entire community.
Then there’s Heihei from Moana. He’s a rooster. He’s... not a genius. His eyes are perpetually pointing in opposite directions, which reinforces that old-school trope that physical misalignment equals mental "slowness." It works for the comedy of the film, sure. Heihei is hilarious. But it’s worth noting that Disney used his eyes specifically to signal to the audience that "nobody is home" in that chicken's head.

On the flip side, look at characters like Ed from The Lion King or even some of the minions in Despicable Me. When eyes don't track together, it immediately creates a sense of chaos.
Why Do Animators Use This Trope?
It's all about "the silhouette" and "the read." In character design, you want the audience to understand who a character is within three seconds. Big eyes mean innocence. Sharp angles mean villainy. Misaligned eyes? They usually mean "unpredictable."
Think about it.
When you can't tell exactly where a character is looking, you feel a slight sense of unease or amusement. It breaks the symmetry of the face. Humans are hardwired to look for symmetry, so when an animator intentionally breaks that rule, they are forcing your brain to pay attention.
In some cases, like with Billy from The Grim Adventures of Billy & Mandy, the drifting eyes just emphasize his high-energy, scattered personality. It isn't necessarily mean-spirited, but it does lean into the idea that a "lazy eye" is a personality trait rather than just a physical condition.
The Reality of Strabismus vs. Amblyopia
Kinda important to get the facts straight here. Most people use the term "lazy eye" for everything, but doctors (and the American Academy of Ophthalmology) differentiate between the two.

Strabismus is the physical misalignment—eyes crossing or wandering.
Amblyopia is when the brain starts ignoring one eye because the vision is blurry.
Cartoons almost exclusively show strabismus. It’s a visual medium, after all. You can’t "see" amblyopia. But for kids wearing eye patches to treat these conditions, seeing a character like the cyclops-like creatures in Monsters Inc. or even a character who just looks a bit different can be a massive confidence booster.
It’s not just about being "derpy."
It's about the fact that according to the Mayo Clinic, about 4% of adults in the U.S. have strabismus. That is millions of people. When every single "hero" character has perfect 20/20 vision and perfectly centered pupils, it sends a subtle message about who is allowed to be the protagonist.
The Shift Toward "Real" Representation
We are starting to see a move away from the "lazy eye = dumb" trope.
Take a look at more modern, indie animations or character-driven shows on platforms like Netflix. Designers are starting to give characters slight physical quirks—like a wandering eye or glasses with thick lenses—without making it their entire identity. It’s just... a thing they have.

In The Mitchells vs. the Machines, the character designs are messy and human. They have eyebags. They have weird teeth. This is where the future of lazy eye cartoon characters lies. It’s about making characters feel like real people rather than polished plastic dolls.
Honestly, the "perfect" look is getting boring.
Audiences are craving authenticity. If a character has a lazy eye and they’re also the smartest person in the room or the one who saves the day, that’s a win. It breaks the old-school Disney mold where physical "imperfections" were reserved for sidekicks, comic relief, or villains.
What You Can Do Next
If you’re a parent of a kid with strabismus or if you’re a creator yourself, there are real ways to change the narrative around these visual differences.
- Audit your media. Look at the shows your kids are watching. If a character has a lazy eye, how are they treated? Is it a joke? Talk about it. Explain that the way someone's eyes look doesn't define how smart or capable they are.
- Support inclusive creators. Look for artists on platforms like Instagram or ArtStation who intentionally design characters with diverse physical traits. The more we celebrate these designs, the more big studios will take notice.
- Reference real-world icons. Remind yourself (or your kids) that plenty of incredibly successful, talented people have or had strabismus—think Forest Whitaker, Ryan Gosling, or Kristen Bell.
- Use the right terminology. Try to move away from "lazy eye" when talking about the condition. Using words like "strabismus" or "eye misalignment" helps destigmatize the physical reality and separates it from the idea of being "lazy" or "broken."
The world of animation is a mirror. For a long time, that mirror was a bit warped when it came to vision issues. But as we move toward 2026 and beyond, the demand for genuine, nuanced representation is only growing. Whether it’s a pony, a rooster, or a human hero, every eye—no matter where it’s looking—deserves to see a bit of itself on the screen.
