Disney Pixar’s latest film, Elio, follows a familiar-sounding character, a lovable and imaginative young hero who dreams of finding a place where he truly belongs. But amid the colour and chaos of the film’s outer space setting, one subtle detail stands out: Elio wears an eye patch.
In the real world, eye patches are commonly used to treat amblyopia, or “lazy eye”, a neurodevelopmental visual condition projected to affect 175.2 million people globally by 2030. In amblyopia, the brain favours one eye over the other, leading to reduced vision in the weaker eye.
Treatment often involves covering the stronger eye with a patch, encouraging the brain to rely on the weaker eye and improve its function. This therapy is most effective during early childhood and can take months of daily commitment.
Yet, despite how common visual conditions are, positive representation of patch-wearing is rare in popular media.
Animated films have long shaped childhood imaginations, but historically, characters with eye patches or other visual markers often fall into negative stereotypes.
Think Mr Potato Head’s alter ego One-Eyed Bart in Toy Story, or Madagascar’s Dr. Blowhole: characters where an eye patch signals villainy. Glasses, meanwhile, are more often seen on older characters like Carl Fredrickson from Up or Roz from Monsters Inc.
Characters with strabismus (misaligned eyes), like Ed from The Lion King, are often portrayed as unintelligent or clumsy. One recent study found that strabismus in children’s animated films is consistently associated with negative character traits – something that can reinforce harmful stigma.
These portrayals matter. Film plays a powerful role in shaping beliefs, especially for young children who are developing a sense of identity, belonging and how to relate to others. When visual conditions are stereotyped, it can reinforce feelings of embarrassment and difference.
For children wearing a patch, these feelings can lead to skipping treatment days and poorer outcomes. In contrast, authentic, positive representation can build self-esteem, promote acceptance, and provide relatable role models.
A subtle but powerful shift
Happily, things are starting to change. In recent Disney/Pixar films, we’ve seen characters with glasses portrayed as dynamic, central figures: Encanto’s Mirabel, Turning Red’s Priya and Mei, and Big Hero 6’s scientist-superhero Honey Lemon, for example. These characters challenge old stereotypes and broaden the narrative around vision.
Elio continues that progress. The young protagonist’s eye patch is not a plot point, nor is it used to symbolise frailty, villainy or wisdom. It simply exists – a quiet part of his identity, not something to overcome.
That subtlety is powerful. For children who wear patches, seeing someone like Elio leading a space mission, not sidelined by his visual condition, can be deeply affirming.
Beyond the screen, Elio has sparked conversation and awareness. Prevent Blindness launched a campaign around the film to raise public understanding of amblyopia and the importance of early detection. Eye care organisations have also used the film as an educational tool, while individuals have shared their stories of patching and treatment across social media.
When amblyopia is recognised and treated early, patching can be remarkably effective. But awareness is key, and so is reducing stigma that might discourage children from wearing their patch.
Childhood amblyopia research
Although patching often restores vision, it doesn’t work for every child – and we still don’t fully understand why. There is limited research into how patching affects the developing brain, and this lack of insight hinders improvements in treatment.
Our research with Holly Bridge, Vision Group leader at Oxford University, aims to change that. We’re studying how patching changes brain chemistry in young children.
Adult studies suggest that chemical shifts in visual parts of the brain may be linked to patching outcomes. To explore this in children, we’re running a study of five to eight-year-olds with amblyopia or healthy vision.
In our study, children with amblyopia receive a safe, non-invasive brain scan before and after patching treatment. We also measure their vision using child-friendly tests. We then compare these results to children with healthy vision who don’t wear a patch, helping us to understand both visual changes and brain development.
We hope Elio marks the beginning of more inclusive storytelling, where difference isn’t erased or exaggerated, but simply woven into the fabric of character and adventure. Like Elio’s journey through space, the path to better understanding and representation of childhood visual conditions has faced challenges.
But perhaps this is the launch we needed: towards better awareness, better research, and a future where every child feels seen – on screen and beyond.
