I have found the fonts at <https://opendyslexic.org/> to be helpful. It is actually harder to read and in turn slows you down, so there are less errors.
I saw another method recently that highlights certain letters in a word to be bold and doesnt need to change the font. The test examples were very easy for me to read.
Unfortunately I didn't bookmark it and now can't find it!
