Which colour ipad will cause less eye strain for heavy reading and browsing? I will not be playing games or watching videos.
I think either color will do since you're looking at the screen, not the frame surrounding it.
I'm sure someone will pipe in with their special case exception, such was watching dimly lit movies in a dark closet and being distracted by a non-black bezel...
Just because you're focussing on the screen doesn't keep the photons from the white border from entering your eyes and decreasing your contrast. It's hard to say what the overall magnitude of the effect is, though, so I wouldn't dissuade anyone from getting white if they just really like white. But based on the OP's original question, I'd would definitely say black is better than white.I think either color will do since you're looking at the screen, not the frame surrounding.
