Who This Tool Is Designed For

Dyslexia is a specific learning disability that affects reading accuracy, fluency, and comprehension. According to the International Dyslexia Association, prevalence estimates range from 5–15% of the population (Shaywitz, 2003). Dyslexia is neurobiological in origin and is not related to intelligence. Individuals with dyslexia often experience difficulties with letter recognition, visual crowding, and line tracking · all of which can be mitigated through typographic adjustments.
