🔍 ABOUT •••••••••••••••••••••••••••••••••••••••••• OpenDyslexic is a free, open-source font designed to make reading easier for people with dyslexia. This extension replaces all fonts on web pages with the OpenDyslexic font, making content more readable and accessible. Sometimes letters can feel jumbled or rotated, making reading frustrating. OpenDyslexic tackles this by giving each letter a heavier bottom, creating a "gravity" effect that helps keep them steady and grounded. This unique design makes it easier to recognize letters and read smoothly. The distinct shapes of the letters also reduce confusion and swapping, so you can focus on reading without the struggle. 📱 STAY CONNECTED •••••••••••••••••••••••••••••••••••••••••• Join our amazing community: Official Website: OpenDyslexic.org Facebook: OpenDyslexic Twitter: @OpenDyslexic 🛠️ MAINTAINER ••••••••••••••••••••••••••••••••••••…
