I have also recently heard that black text on white is not ideal for people with astigmatism (although I am one and have not noticed this effect).

Hi,

Sorry, writing in English is difficult for me, but I'll try.

I spoke several times about this problem in conferences, however I have
not found many resources...
I have shown that the strict compliance with WCAG about contrast does
not produce an accessible site for some people, such as dyslexic.

I'm dyslexic, with scotopic sensitivity syndrome.
For me white letters on black background appear twinkle, and the words
seem to move ... I am unable to read (except for some words in large
font, as a short title)

Best regards,
Monique
