Reading and Writing

For many adults, reading and writing come so naturally that they seem almost effortless. However, reading and writing are actually complicated skills that take significant effort to learn. For example, reading involves recognizing letters, associating letter combinations with their corresponding sounds, blending sounds together, identifying words, and connecting words to their meanings. Vision problems can interfere with several portions of this process, resulting in significant reading or writing deficits that may be diagnosed as learning disabilities.

Symptoms of Reading and Writing Difficulty

There are many reasons that kids might experience difficulty with reading or writing, but it is important to rule out vision impairment. Common symptoms of vision-related reading and writing problems include:

• Reporting that words appear blurry or shimmer on the page
• Words “swimming” or switching locations
• Low attention span for reading and writing tasks
• Behavioral outbursts when asked to read or write
• Eye strain
• Headaches after short periods of reading or writing
• Poor grades in reading and English classes
• Making spelling errors
• Problems recalling the sequence of letters or numbers

Common Vision Problems Affecting Reading and Writing

Several vision disorders can negatively impact reading and writing, including the following:

• Refractive disorders. Farsightedness, nearsightedness, and astigmatism lead to poor visual acuity. This may make it difficult to clearly see written words.
• Convergence insufficiency. Convergence insufficiency is a function vision problem in which the two eyes do not stay aligned, particularly when doing close work.
• Eye movement disorders. Effective reading and writing require smooth, synchronized eye movements. Problems with the eye muscles or execution of these eye movements may significantly impair reading and writing abilities.
• Accommodative dysfunction. If the eyes do not focus accurately, words may appear blurred or may seem to move on the page. While children may be able to focus well when concentrating hard, this often leads to eye strain.

Vision Therapy for Reading and Writing Problems

Vision therapy offers an opportunity to teach the eyes to work more typically. Performed in an eye doctor’s office, vision therapy involves performing special tasks to correct vision disorders. This might include corrective lenses, prism lenses, computer tasks, focusing exercises, or eye movement tasks.

Over time, completing vision therapy exercises retrains the eyes and brain to work together more effectively. Vision therapy can correct many of the problems that lead to reading and writing difficulty, resulting in improved academic performance and better visual attention.
