OpenDyslexic font was developed to make reading easier for individuals who have dyslexia. There are different types of dyslexia, and this font doesn't help everyone, but it can help some, especially for those who's dyslexia manifests in their visual interpretation of letters, numbers, and symbols. There is some controversy about whether this font actually helps, but since dyslexia is really a group of different symptoms, philosophically, it can't hurt.
The font has weighted letters that help "anchor" them in place on the page or screen. This means they might not "spin" or "flip" around as much for those with visual dyslexia symptoms.
We started using the font in 2017, after one of our authors discovered it, and asked if we could use start using it. It sounded like a plan, and we forged ahead. After all, reading should be pleasant and fun for anyone who wants to read.
We've had some folks comment that it looks odd, and what if it's hard to read? [!?!?!?] We explain that though it may take a couple of pages to get used to, it doesn't seem difficult to understand, and... why not take a little time to assimilate if it means those who need it, have access to it?
Don't worry -- we try to be nice when we explain.
And a lot of folks love the concept. Wow!!!
