I believe that using screens particularly lcd ones causes sloth and torpor in the mind, be it the low frequency of most devices (60hz) or the type of light and its constant in particular. The effect are pressure in the meninges, spacing out, loss of interest in the physical, magical thinking, reduction of gray matter. The thing that could be affecting me are a bad posture or the low frequency update of my screen. I can see that the effect reduces if lay down using my phone which is a way smaller oled screen. Im considering switching to a 240hz crt monitor or indirect sources of light like a projector or a e-ink screen.
