Dyslexia is a widely recognized learning difficulty that affects reading, writing, and spelling. However, many parents may not realize that certain vision problems can mimic the symptoms of dyslexia, leading to misdiagnosis or overlooked treatment options. If a child struggles with reading, reverses letters, or has difficulty focusing on words, it may not be a learning disorder—it could be an undiagnosed vision issue.

The Overlap Between Vision Problems and Dyslexia

Children with undiagnosed vision issues may experience challenges similar to those with dyslexia, including:
 

• Skipping words or lines while reading
   

• Reversing letters or numbers
   

• Difficulty maintaining focus on the page
   

• Poor reading comprehension
   

• Frequent headaches or eye strain

These symptoms can be caused by functional vision problems, such as eye tracking difficulties, convergence insufficiency, or accommodative dysfunction. Unlike standard visual acuity issues (like nearsightedness or farsightedness), functional vision problems affect how the eyes work together and process visual information.

The Importance of Pediatric Eye Exams

A standard vision screening may not detect functional vision problems. This is why comprehensive pediatric eye exams are essential. At East Main Vision Clinic, we go beyond checking for 20/20 vision to assess how the eyes function as a team.

Early detection of vision problems can prevent unnecessary frustration in the classroom. If left undiagnosed, these issues can impact academic performance, self-confidence, and even behavior. Children struggling with reading or writing should have their vision evaluated before assuming a learning disorder is the cause.

What Is a Functional Vision Evaluation?

A functional vision evaluation is a specialized assessment that examines how well a child’s eyes work together to process visual information. This in-depth evaluation assesses:
 

• Eye tracking – the ability to follow words smoothly across a page
   

• Eye teaming – how well both eyes work together to maintain focus
   

• Eye focusing – the ability to switch focus between near and far objects
   

• Visual processing – how the brain interprets what the eyes see

If a functional vision issue is detected, vision therapy may be recommended. Vision therapy is a structured program that helps strengthen the connection between the eyes and brain, improving reading skills, coordination, and overall visual function.

Schedule Your Child’s Eye Exam Today

Before assuming a child’s reading struggles are due to dyslexia, it is crucial to rule out vision problems as a contributing factor. Undiagnosed functional vision issues can lead to similar academic difficulties but are treatable with proper intervention. A functional vision evaluation can provide the clarity needed to support a child’s success in school.

If your child is experiencing difficulty with reading or learning, contact East Main Vision Clinic to schedule a functional vision evaluation. Visit our office in Puyallup, Washington, or call (253) 780-0700 to book an appointment today.
