Outdoor classroom with children attentively listening to the teacher—one girl is doing a handstand, acting out due to undiagnosed vision problems that can mimic ADHD and lead to mislabeling in school settings

Before You Say Yes to ADHD Testing, Learn What Her Little Eyes Might Be Telling You

Author: Hayley Martin 

 

For every parent who’s heard: “Your child might need to be tested for ADHD…”

It’s a moment that can stop your heart.

The teacher sits across from you, maybe with a gentle smile or a worried frown, and says the words: “We think your child may have ADHD.” Or “She’s struggling to focus. You might want to look into testing.”

Suddenly the ground feels unsteady. You think of your sweet child, so imaginative, so sensitive, so full of dreams, and you wonder if something is truly wrong.

At Once Upon a Charm, we want to whisper something both magical and true. Before you assume the story is about attention, it might be about vision.

In this classroom scene, one child disrupts while others focus—reminding us that what looks like misbehavior may be a sign of undiagnosed vision problems. A gentle prompt for parents and educators to look deeper.

The Overlap No One Talks About: ADHD and Vision Problems

Teachers care deeply about helping children succeed. When they see a student who can’t sit still, who drifts off during lessons, who is behind in reading, or who doesn’t follow instructions, it’s only natural to consider attention issues.

But many of the signs associated with ADHD or ADD, difficulty focusing, avoiding tasks, rushing, fidgeting, frustration, can also be caused by undiagnosed vision problems.

These include:

These are not tested in standard school screenings. So, a child might pass the vision check and still be struggling to see.

Quiet classroom of girls reading peacefully—one girl avoids her book, stacking objects on her desk instead. Her behavior may be mistaken for ADHD, but undiagnosed vision problems like blurry or moving text could be the real reason she’s struggling to read.

Why These Vision Challenges Look Like ADHD

Imagine trying to read while the words shimmer, skip, or blur. Imagine looking at your teacher, then down at your desk, and needing several seconds just to focus your eyes again. Imagine your eyes working twice as hard just to stay aligned.

Now imagine doing that for hours a day.

You might squirm. Daydream. Rush through tasks. Seem forgetful. Or give up entirely.

Not because you don’t care, but because your visual system is quietly, invisibly overwhelmed.

When this happens, it’s not a lack of attention. It’s a lack of clear, comfortable vision. But unless a developmental optometrist checks the right things, no one may know.

 

“But She Passed Her Vision Screening at School…”

It’s one of the most common, and heartbreaking, misunderstandings.

Most school or pediatrician screenings only test acuity. That means reading letters on a chart from across the room. But learning, especially reading, is a near-vision task.

Children also need to:

  • Focus both eyes at the same time
  • Move their eyes smoothly across a line of text
  • Shift focus from board to book and back again
  • Understand and process what they see

If any of these skills are weak, learning becomes harder. So, it's important to be aware of the fact that none of these functions are tested in standard vision screenings.

That’s why so many parents are told, “Everything looks fine” even when their child is struggling to read, pay attention, or keep up in class.

In fact, The American Optometric Association reports that 75% of school vision screenings miss vision problems.

 

Child receiving a vision screening at school—while helpful, these screenings only detect a few basic issues. A comprehensive pediatric eye exam is essential to uncover deeper vision problems that screenings often miss.

 

Before the ADHD Evaluation, Try This

If your child’s teacher has recommended testing for ADHD or ADD, consider one important first step: Schedule a comprehensive eye exam with a developmental or pediatric optometrist.

These specialists evaluate how well your child’s eyes work, not just how well they see.

They can detect:

  • Hidden eye teaming issues
  • Near-point stress or fatigue
  • Tracking problems
  • Visual perceptual delays

If a problem is found, the solution might be as simple as a pair of glasses, or as gentle as vision therapy that retrains the eyes and brain to work together.

And if no visual issue is found, you can move forward with other evaluations feeling confident you didn’t miss something vital.

 

You’re Not Alone. And There Is Hope

Hearing that your child might need to be tested for ADHD can feel devastating. It’s natural to worry. It’s natural to want to fix it fast. But sometimes, the answer lies not in attention or behavior, but in how the world looks through your child’s eyes.

We’ve met countless families who’ve said, “She just seemed distracted,” or “He hated reading,” only to discover that it wasn’t attention at all. It was vision.

And once their child could see clearly, everything began to change.

Confidence bloomed. Frustration faded. Reading became joyful. Focus came naturally.

 

See the Possibility

It may be time to look beyond labels and check for something gently correctable, if your child is showing signs like:

  • Difficulty focusing in class
  • Trouble with reading or writing
  • Frequent headaches or eye rubbing
  • Squinting or covering one eye
  • Avoiding close work
  • Being labeled as inattentive or disruptive

A comprehensive eye exam is a loving, low-stress place to start.

A new pair of glasses could be a life-changing gift.

And if your little one does need glasses, we’re here to make sure it's a magical experience for her.

A New Way to See Her Story

The road to discovery can feel long. But with each gentle step, your child is not falling behind, she is finding her way.

And sometimes, the very thing that seems like a setback, is actually the start of her becoming.
