I was under the impression that Visual Snow was a symptop of anxiety?

  anxiety is a symptom of an underlying nervous system dis-order. so staring at a screen for long periods of time is hard on an organisms nervous system (to remain in place for so long without movement). So visual snow and anxiety both stem from the underlying structure being at dis-ease.

  Visual snow could also be to to flickering from PWM, or more likely temporal/spatial dithering (a leading theory in LED LCD based eyestrain but as yet unproven as the cause). Even a white background on a monitor, even a static image, isn't just static white...it's constant flickering of pixels to make a certain "white" and to smooth moving images as well. Whatever the ultimate cause it's not normal or healthy to stare at emitted light most of the day and most of us do...add flickering and other visual tricks displays use and it's no wonder eyestrain exists. Nobody would stare at a 300 nit lightbulb for hours and call that reasonable, but that's what backlit LCD displays are. I didn't have a problem for most of my life, and still don't with books under proper lighting, but now I have a severe one with LCDs that and cannot find a definitive answer or fix and frankly it's crushing a last chance I have to be somewhat independent and survive.
