Dyslexia and Vision
Understanding Visual Challenges in Children with Dyslexia
- Words appear to move, blur, or swim on the page
- Losing place frequently when reading
- Skipping words or lines of text
- Rereading the same line without realizing it
- Headaches or eye strain during reading
- Rubbing eyes or excessive blinking while reading
- Avoiding books or reading tasks
- Reading difficulties increase when eyes cannot track smoothly
- Decoding struggles worsen when focus is unstable
- Comprehension suffers when visual effort is exhausting
- Spelling errors increase when visual memory is weak
- Writing difficulties compound when visual-motor integration is poor
- All reading problems are attributed to dyslexia
- Standard eye exams show clear 20/20 vision
- Children assume everyone sees text the same way
- Reading specialists may not consider functional vision
Possible Causes
- Differences in how the brain processes language
- Phonological processing weaknesses affecting decoding
- Difficulty connecting sounds to written symbols
- These are real and valid aspects of dyslexia
- Eye tracking problems make following a line of text exhausting
- Convergence insufficiency causes words to blur or double
- Focus flexibility issues create strain when reading
- Eye teaming problems lead to visual fatigue and avoidance
- Visual processing deficits affect letter and word recognition
- Dyslexia and visual dysfunction both cause reading difficulty
- Symptoms overlap and reinforce each other
- A child may have dyslexia, visual problems, or both
- Treating only one leaves the other barrier in place
The Vision Connection
- Reading already requires enormous effort for children with dyslexia
- Adding visual strain makes reading nearly impossible to sustain
- The brain fights two battles at once
- Frustration and avoidance increase
- Addressing vision removes one barrier to reading success
- Smoother tracking makes following text easier
- Stable focus reduces fatigue and headaches
- Reading intervention becomes more effective when vision is efficient
- Standard exams test distance sight, not reading vision
- Eye tracking, teaming, and focus flexibility are not assessed
- Visual processing skills are not part of typical screenings
- A child can have perfect 20/20 vision and still struggle to read
Evaluation and Treatment
- Eye tracking across a line of text
- Eye teaming and convergence ability
- Focus flexibility and sustained focus
- Visual processing speed and accuracy
- Visual memory and discrimination
- Visual-motor integration for writing
- Individualized programs targeting specific visual deficits
- Treatment designed to complement reading intervention
- Neuro-visual performance training builds efficient visual pathways
- Intensive in-office programs with remote follow-up
- Collaboration with tutors and reading specialists when possible
- Orton-Gillingham and other programs work better when vision is efficient
- Decoding practice becomes less exhausting
- Reading stamina increases when visual fatigue decreases
- Comprehension improves when less energy goes to visual mechanics
Questions and Answers
No. Vision therapy addresses how the eyes and brain work together for reading tasks. It does not treat the language processing differences that define dyslexia. However, removing visual barriers can make reading intervention significantly more effective and reduce the overall struggle.
Many children have both. A developmental vision evaluation can identify whether functional vision problems exist alongside dyslexia. If visual issues are found, addressing them shows how much of the reading difficulty was visual versus language-based.
Yes. School screenings test distance sight, which is not what reading requires. A child can see 20/20 on a wall chart and still have significant problems with tracking, teaming, focusing, and visual processing that make reading extremely difficult.
Convergence insufficiency is when the eyes struggle to turn inward together for close-up tasks. This causes words to blur, double, or move on the page. It leads to eye strain, headaches, and reading avoidance. Research shows it is highly treatable with vision therapy.
Both can happen at the same time, and often this is ideal. Vision therapy builds the visual foundation while reading intervention addresses language skills. Many families find that reading progress accelerates once vision is also being addressed.
Some children with dyslexia do need glasses, but glasses alone do not address functional vision skills. Tracking, teaming, focus flexibility, and visual processing require vision therapy to develop. Glasses and vision therapy often work together as part of a complete plan.
I haven't seen crisply in 23 years. I could read close up or far away until 25. My eye doctor connected a past car wreck to my vision loss and referred me to NVPI. After 30 weeks, I see clearly again--details everywhere. NVPI changed my life; I’m forever grateful.

My children absolutely loved going here! Everyone is super nice!

We saw a huge improvement in reading comprehension, balance, coordination and quite a few other things. We found out that a lot of the anxiety and confidence issues that our son had dealt with for years were directly tied to his vision struggles. This was a huge surprise to us. Very glad we found our way to Dr Graebe and his team.

We couldn’t be happier with the Vision Therapy services that our daughter has received working with Jennifer! She has experienced so many improvements in her everyday life, had fears diminished with her confidence she has gained from therapy and she is better able to engage with others! I highly recommend NVPI’s services and therapies; it will change your life or your loved one’s life for the better!

My children absolutely loved going here! Our insurance stopped being accepted was the only reason they stopped going! Everyone is super nice!
