I can't stand neon light and supermarkets make me feel totally disoriented. But as an IT professionnal and internet dweller, I spend up to 12 hours a day behind a computer monitor and that does contribute to my DR feeling quite a bit. Flat-panel monitors are easier to bear, in this respect and that must be because their refresh frequencies are usually higher than those of cathodic monitors. Or is it because diode light is less debilitating than cathodic tube light? Are there physicists in here? What differenciates these two sorts of light besides, perhaps, their wavelengths? More down to earth, how do you geeks cope with that problem? Like most software developers, I have a compulsive need for coffee when I'm designing or programming. I stumble my way to the coffee machine like a zombie, annihilated, walk into people, mumble an apology, I forget I even exist while looking in my pocket for change, putting the coins in the slot and waiting for my coffee. I walk back to my office, sipping that disgusting watery coffee, avoiding to look people in the eyes, my visual focus is completely off, like non-existant and exploded at the same time, I finally crash on my chair and slip back into my imaginary world made of C++ code, behind that TFT monitor.
That's my experience of DP/DR and computer monitors.
