I have a 2014 Kindle Basic 7th generation that has never been updated and I am able to use it without any problems.

I had the same model some years ago and when it was updated in 2022, I could no longer use it (brain fog and fatigue).

All other newer e-readers of any brand that I have tried, as well as older e-readers that have been updated, I am unable to use.

Do all current e-readers use anti-aliasing (font smoothing), and does my never-updated Kindle Basic 7th generation not use it?

If current e-readers use it, is there a way of turning it off on all or some of them?

Would be grateful for your help!
