Re:Ask HN: How do you prevent headaches from screen use? by comprambler on Monday November 23, 2020 @12:30AM (#25183871)
Created an account to respond to this as I get headaches from any of the below triggers

Non interlaced sources

No 50hz refresh battery saver crap

IPS monitors over TN

Look up PWM as a backlighting tech, a bad source

Lighting in your room, PWM can come into play here again in the switch

Bad flourescents

Good luck.
