Zodios I agree, I always inspected my eyes in the mirror and it was clearly visible under high strain situation, eyes looked popped out with high preasure. But I believe its a chicken and egg situation. And I was about to share Today, that PSR (Panel Self Refresh) is ways more important cause then PWM or temporal dithering (Old and new laptops). Those folks in other posts who have shared how macbook flickers when image is playing in the background, and when it does not, and how this affect the flicker, are living proof of that. So, beyond tackling health side of things, I think it is really important to make sure at least devices are used/modified in order to cause least amendment of a natural healthy state. (Apart from obiously factors beyond technology, such as focus, posture, coffee overdose, overwork, etc.)
