OpenDyslexic

OpenDyslexic is a new open source font created to increase readability for readers with dyslexia. The typeface includes regular, bold, italic, and bold-italic styles. It is being updated continually and improved based on input from other dyslexic users. 

OpenDyslexic Mono is included for programming, or other areas where a fixed width font is preferred. 

OpenDyslexic 3 is now available in Regular and Bold! OpenDyslexic 3 is a ground-up redesign of OpenDyslexic, taking into account recommendations from educators, teachers, and other users. It is released under the SIL-OFL license.

There is a new version of OpenDyslexic

It's licensed as SIL-OFL to make it easier to include in projects where other licenses caused difficulty.

It's included in the downloads now as a free update and includes the OTF and WebFont versions.
