Why Simulate Dyslexia? Because Empathy Starts with Experience
Dyslexia affects about 10% of the population, yet most people have zero idea what it’s actually like. Reading is so automatic for most of us that we take it for granted. These simulations aren’t just educational—they’re empathy generators. When you see letters dance, swap, or blur, you’ll never look at a page the same way again. Plus, for designers and developers, understanding these visual barriers is the first step to creating truly accessible content.
