Dyslexia is not a vision condition, and eye doctors do not treat dyslexia. However, the connection between dyslexia and vision is important for parents, educators, and healthcare providers to understand. Many children with dyslexia also have vision problems that can make reading even harder.
Dyslexia and vision problems share many of the same symptoms. Children with dyslexia are also far more likely to have a vision deficit. Research suggests that approximately 62% of children diagnosed with dyslexia also have eye tracking disorders. Studies from Harvard Medical School and Boston Children's Hospital found that 79% of children who struggle with reading also face problems with binocular vision and eye coordination.
Statistics show a concerning overlap between dyslexia and vision problems. Common symptoms of both conditions include headaches, fatigue while reading, difficulty maintaining attention, and confusion with similar letters like 'b' and 'd.' Many eye conditions can present similarly to dyslexia. Some research suggests that 13 out of 17 symptoms of dyslexia are also associated with vision disorders.
A developmental eye exam can reveal whether the underlying issue is vision related. It can also show if there is a vision problem in addition to dyslexia that makes reading more difficult. Because dyslexia and vision problems overlap so often, scheduling a comprehensive developmental eye exam is an important step for any child struggling to read.
Common symptoms of both dyslexia and vision related learning disorders include:
Signs of dyslexia include slow and labored reading, difficulty with spelling and frequent errors, struggles with multi-syllable words, difficulty with phonological awareness, poor reading comprehension, and avoiding reading tasks.
Signs of vision issues that impact learning include visual discomfort or headaches from reading, skipping or repeating lines of text, avoiding reading, slow reading with poor comprehension, regular eye strain, and head tilting or covering one eye while reading.
Because symptoms overlap so much, it can be hard to know if a child has dyslexia, a vision problem, or both. A thorough evaluation by qualified professionals can help identify the true source of reading difficulties. Many children benefit from addressing both issues at the same time.
Children need to use their eyes effectively to track text smoothly and comprehend reading material. Poor eye teaming can prevent proper alignment and focus. When the eyes do not work together well, reading becomes tiring and frustrating.
If a child's brain struggles to interpret visual information, they may be unable to recognize letters and words quickly. Quick recognition is essential for fluent reading. Visual processing problems can slow down reading and hurt comprehension.
The ability to coordinate visual input with motor actions is vital for writing and other school tasks. Challenges in this area can affect a child's performance across many subjects, not just reading.
Dyslexia is one of the most common learning disabilities. It affects about 1 in 8 students in the classroom. However, fewer than 1 in 10 children with dyslexia are formally diagnosed. Many children struggle without knowing why.
Multiple studies suggest that between 6% and 16% of children may have eye tracking or binocular vision deficits. Binocular vision dysfunction is estimated to impact 1 in 5 school aged children. Common conditions include:
Children with learning or behavioral issues have higher rates of vision problems. A 2021 meta analysis found that over 50% of children with dyslexia have eye movement dysfunction. Research from Harvard Medical School showed that 79% of children who struggle with reading also face problems with binocular vision. Studies also showed that children with ADHD were three times more likely to have binocular vision issues.
Symptoms of dyslexia and vision disorders can overlap, making it important to check for vision deficits. While dyslexia is a language based learning disability, many children with dyslexia also face underlying vision issues that can make reading harder. A thorough pediatric developmental eye exam can help determine if your child's challenges come from a visual processing disorder. Standard vision screenings often miss these problems.
Diagnosing dyslexia is rarely straightforward. Many symptoms associated with dyslexia, such as slow reading speed, frequent spelling errors, and difficulty understanding complex texts, can also be caused by vision problems that go unnoticed. Some children diagnosed with dyslexia respond positively when their visual problems are properly treated.
Understanding that dyslexia and vision issues often occur together is important for helping us help children succeed. Even though vision therapy does not treat dyslexia itself, fixing a child's visual challenges often results in noticeable improvements in reading fluency and comprehension for dyslexic children who also have vision problems.
Dyslexia is a learning disability that primarily affects reading, writing, and spelling. This disorder arises from difficulties in processing language and does not reflect a person's intelligence. A child with dyslexia may struggle with recognizing letters, decoding words, or recalling vocabulary. This often leads to frustration and low self esteem.
One common myth is that dyslexia results from poor teaching or lack of effort. Dyslexia is actually a neurobiological condition. It is not tied to low intelligence. Even children with 20/20 vision can experience severe visual processing issues that contribute to dyslexia symptoms. Vision disorders can mimic or worsen dyslexia, making it important to explore all possible causes.
Dyslexia refers to a cluster of symptoms that cause difficulties with specific language skills, particularly reading. This condition often coexists with visual processing issues. Common indicators include:
Treating dyslexia often requires a team approach that brings together different therapies to support the child's learning needs. For many children with dyslexia, underlying visual conditions can affect their reading abilities. Treatment options include:
Vision therapy is a personalized program that focuses on improving the visual skills needed for reading and learning. At Insight Vision Center Optometry, Dr. Valerie Lam, OD, FAAO, FOVDR provides vision therapy through The Eye Gym at Insight Vision Center Optometry. Vision therapy addresses issues like:
Children who complete vision therapy often experience significant improvements. Benefits include:
No. Vision therapy does not cure dyslexia because dyslexia is a language based learning disability, not a vision condition. However, if a child with dyslexia also has a vision problem, treating the vision issue can make reading easier and help other dyslexia treatments work better.
We recommend children have their first comprehensive eye exam around age one, then again at age three, and before starting school. If your child is struggling with reading or showing signs of a learning difficulty, schedule a developmental eye exam regardless of age. Early detection leads to better outcomes.
Not necessarily. Many vision problems that affect reading are related to how the eyes work together, track text, or process visual information. These issues are often treated with vision therapy rather than glasses. Some children may benefit from both.
Vision therapy programs typically last several months, with sessions once or twice per week. The length depends on the specific vision problems being addressed and how the child responds to treatment. Our optometrists will create a personalized plan and adjust it as your child progresses.
Standard eye exams check for clarity of vision and eye health but often miss problems with eye teaming, tracking, and visual processing. A developmental or functional vision exam is more thorough. It tests how well the eyes work together and how the brain processes visual information.
Yes. Because vision problems can mimic dyslexia symptoms, it is wise to rule out or identify vision issues first. If a vision problem is found and treated, some reading difficulties may improve. If your child still struggles after vision treatment, dyslexia testing would be the next step.
