Dyslexia-friendly fonts typically have larger x-heights and wider spacing to improve letter differentiation and reduce visual crowding. They may also have unique letter shapes or heavier weights to make them more legible.

Found here, which goes deeper into how dyslexic-friendly fonts help people with dyslexia (and yes - comic sans, one of the world’s most hated fonts, is a dyslexic-friendly font)

Not an expert, but the way I understand it is that, instead of b and d looking the same, and p and q looking the same, all rightward facing loops are italicized, and all leftward facing loops are left very round, so a brain that has trouble with mirroring images won’t get confused. They also use serifs, so a capital I and a small L aren’t similar.

Can I ask if you can provide a link or three or so to refer to relevant dyslexia friendly fonts?

I happen to have a very mild form of dyslexia, where either written or typed, I’ll sometimes mix up my lowercase ‘u’ and ‘y’

I always catch the mixup within less than a second and correct it before I ever post, but yeah I’m kinda interested in this question myself.
