Why Explore Dyslexia Simulators?
Dyslexia affects about 1 in 5 people, yet most of us have no idea what it feels like to read with it. Simulators bridge that gap. They scramble letters, distort spacing, and blur lines to recreate the cognitive load that dyslexic readers face daily. For educators, they build empathy; for designers, they test readability; for curious minds, they offer a glimpse into a different way of processing words. These 20 tools range from simple web pages to full-featured apps — each one a window into a world where reading isn’t automatic. Ready to see through new eyes?
