Anti-aliased fonts … damage eyesight.
Are you an optician? A consultant at an eye hospital? Or someone with no medical qualifications who reposts ancient stuff they find on the web?
If you really believe that “Anti-aliased fonts … damage eyesight” then please give us some proof other than the web page you posted. A paper from the peer-reviewed medical literature (eg The Lancet) will be fine.
The article is five years old and actually says
"Perhaps, antialiased fonts will look good on very high pixel density screens, one day, when such screens are widely used, because they would need to create less blur to render, but at the moment, on usual displays, it makes text look worse instead of better. Though, with very high pixel density, aliased rendering will also show very good results."
I think that we are well into “very high pixel density screens” these days.
