Without blue light filter, after prolongated usage, my eyes start to water and itch. It makes me very uncomfortable.
But with blue light filters like flux and Qredshift, I use dimming and filtering 24/7.
I never have aforesaid problems when I am using filters and dimming.
I have also started to use ambient lighting (just a $4 table lamp) behind the screen. This makes things better.
So, with the lowest brightness allowed with no filters or dimming, I start to face unavoidable peoblems after about four hours of usage.
OTOH, with 24/7 use of flux or qredshift, I can comfortably undergo screen time for 14-15 hours.
I would also like to mention that I have seen difference in being able to sleep.
