> On the other hand, you could be myopic and under-corrected - and so suffer more when the pupils are relaxed (similar to the Night Myopia effect).
This is really interesting. I am severely myopic and have always preferred a black background.
However, last week I had cataract surgery and now with a +27.5D (!!) IOL implant in my right eye - the only eye I have, I'm not so nearsighted as I used to be (20/80 now instead of 20/200), but I am still experiencing eye strain when looking at the computer for any length of time. After switching my editor to a white background, things got a lot easier to see.
Mind you, I am only a few days post-surgery and I haven't yet gotten new glasses. I was also having a lot of issues with colorblindness and contrast sensitivity, as well as a lot of "double" vision (which was more accurately "I see 8 of those things" vision). These are now resolved, as well. All of those will factor into the equation a great deal, I'm sure, but I do find that after the cataract surgery, the light background makes for less eye strain.
I switched color schemes from "Blackboard" to "Dawn" but my Blackboard theme may have been modified a bit. I've been using it for so long, I can't remember. It almost seemed as though there were too much contrast with the dark background.
I'm still not at a point where I can use the computer for more than about an hour at a stretch. It's amazing how mentally and physically taxing adjusting to better vision can be.
