This is fascinating! The Braille Institute has developed a font - free to download - that's designed to be clearer for readers with lower vision.
An example of one of the aspects of low legibility that they tackled attached.
It's named Atkinson Hyperlegible. Atkinson was the Institute's founder - https://en.wikipedia.org/wiki/J._Robert_Atkinson

@DD @hildabast @tombofnull I'm trying to come up with a design for a dyslexic Arabic font and I'm disheartened with the progress so far, and how regular fonts can do the same job with some adjustments.
The design goals for the common dyslexic-friendly fonts are to differentiate similar characters (like bdpq) as much as possible and with extra thickness for the baseline (feets) and wider openings (counters).
But extra letter spacing (tracking) and line spacing (leading) is more effective.
The second solution can be applied for more fonts, alongside high contrast solution and bigger text size. People affected with dyslexia can read serif fonts just as well as sans serif. It's a field that desperately needs more serious research: if there were general design practices that favor dyslexic readers that would provide them with far more options than what's currently suggested.
This solution for lower vision diverges in many ways from commonly cited dyslexic fonts (but those are not necessarily what dyslexic people prefer) and embraces serifs for capital i, exaggerated asymmetric shapes yet they still feel familiar (the function is not just "serious", but also "recognizable"), differentiates commonly confused pairs too and can be tested with a gaussian blur filter (although words would blend with low tracking)...
I think it's better.
