While dyslexia is a language-based learning difference, Visual Stress (sometimes called Meares-Irlen Syndrome) is a neurological visual processing issue. The two can overlap significantly, and up to 80% of children with dyslexia also suffer from visual abnormalities. If a child is misdiagnosed with only dyslexia, phonics tutoring may fail because the underlying visual environment—the words moving, vibrating, or glaring on the white background—remains untreated.
