Why Simulating Dyslexia Matters
Dyslexia is not about intelligence; it’s a different wiring of the brain that makes decoding text unusually difficult. When you personally experience the jumbled letters, the words that seem to swim on the page, or the exhaustion after reading a single paragraph, something clicks. You stop seeing dyslexia as an excuse and start seeing it as a daily hurdle. These simulations are not perfect—they’re approximations—but they build bridges. They help teachers choose better fonts, designers create accessible websites, and employers understand why a brilliant employee might need extra time on a report. By spending just a few minutes with these tools, you become part of the solution.
