Amazing, it had the exact polar opposite effect for my eyes. I often have trouble keeping my place in black and white text. I find it like trying to focus on a single conversation in a pub but I end up hearing everyone at once.

If you don't mind me postulating, I wonder whether this difference is something intrinsic to the focussing effect of binocular vision, or if your field of view has maybe trained your brain to be more urgently perceptive to peripheral vision?

then again, maybe its just colour perception.. or different strokes (and thanks, I just learnt about binocular summation.. fascinating)
