Vision Is More Than Just Seeing Clearly
When most people hear the word “vision,” they think of eyesight—how clearly they can see an object in the distance or read a line on a chart. But that’s only part of the picture. Visual acuity is just one small aspect of what makes up our visual system.
For many nonspeaking or unreliably speaking individuals, functional vision—not clarity—is the challenge. Most of the children I work with pass standard pediatric vision screenings with ease. Yet they struggle daily with visual skills like eye teaming, convergence, and tracking—all essential for spelling and communication.
These hidden visual processing issues often fly under the radar because they aren’t detectable with a basic eye chart. That’s where functional vision assessments become essential.
What Is Functional Vision—and Why Does It Matter for Spellers?
Functional vision is about how well the eyes work together: can they stay focused on a single point, follow movement smoothly, and maintain alignment over time? These skills are critical for spelling on a letterboard or keyboard.
Parents often ask, “How can my child get a vision evaluation if they can’t speak?” Fortunately, developmental optometrists trained in assessing non-speaking individuals do exist. Many are learning more about Spellers Method and whole-body apraxia—and are eager to help.
Think about how toddlers, who can’t verbally describe their vision, still get diagnosed and treated. The same is true here—there are tools to assess visual function without relying on spoken feedback. You just need the right provider who understands—or is open to understanding—your child’s unique communication and motor profile.
Spelling Requires More Than Intelligence—It Requires Vision Skills
For individuals with whole-body apraxia, pointing to letters isn’t just a motor task—it’s a visuo-motor task. Spellers must coordinate their eye movements to locate each letter before directing their hand to point accurately.
Many of my clients struggle with visual endurance. Even though their minds are sharp, their eyes fatigue quickly. The tiny muscles controlling eye movement tire out faster than larger muscles, which is why you might see a drop in accuracy mid-session.
What appears to be disinterest or poor attention is often visual fatigue. That’s why building ocular motor stamina—through consistent, guided spelling practice—actually strengthens their visual system. Spelling itself becomes both a communication tool and a form of visual-motor therapy.
Vision and Self-Regulation: The Hidden Link
Here’s a connection many people don’t realize: unstable vision can lead to dysregulation. Many spellers who appear fidgety, restless, or impulsive are actually trying to compensate for poor visual integration.
When the central and peripheral vision systems aren’t working in harmony, the brain becomes overwhelmed. The body often responds with movement—rocking, shifting, pacing—because physical motion re-engages peripheral vision and helps restore balance.
If a child can’t maintain a steady gaze on the letterboard, they may become frustrated or overstimulated. Rather than labeling these responses as “behavioral,” it’s crucial to recognize them as signs of visual disintegration and nervous system dysregulation.
Supporting the visual system can lead to better regulation, smoother motor planning, and more consistent communication.
Finding a Vision Specialist Who Understands Apraxia and Spellers
Parents frequently ask, “Where do I find a developmental optometrist who understands my child’s needs?” It’s a great question—and a critical step in supporting your child’s spelling journey.
Start by visiting the Neuro-Optometric Rehabilitation Association (NORA) website. Look for practitioners with the FCOVD credential, which indicates specialized training in functional and developmental vision care.
But remember: credentials are only part of the equation. It’s essential to speak with the provider directly. Ask whether they’ve worked with non-speaking individuals or those with neuromotor challenges. If they seem curious and open to learning—that’s a great sign.
Many assessments won’t be covered by insurance, so ensure the provider is a good fit before investing time and money. A great resource to share is the webinar by Dr. Susan Daniel, where she walks through a full vision exam tailored for individuals with apraxia. Even if your local provider isn’t familiar with spelling, this video can bridge the gap.
Helping Spellers Thrive by Supporting Visual Processing
Spelling is more than mental effort—it’s a complex visual and motor process that requires stamina, coordination, and regulation. If your child struggles with pointing accuracy, becomes easily fatigued, or appears dysregulated during sessions, vision might be the missing piece.
Improving visual processing doesn’t just support spelling—it enhances overall communication, body awareness, and self-confidence. With stronger visual-motor control, your child can focus longer, spell more accurately, and regulate more effectively.
Final Thoughts: Don’t Underestimate the Power of Vision
Vision is one of the most underrated factors in spelling success. It’s not just about being able to see—it’s about how the brain and eyes collaborate to create meaning, guide movement, and maintain attention.
If you suspect your child has functional vision issues, don’t wait. Finding a knowledgeable developmental optometrist can open new doors for communication, learning, and connection.
By addressing visual processing alongside motor development, we can help every speller unlock their full potential—one letter at a time.
