Color Difference between Left and Right Eyes?
I have this, too, just as several previous posters described. It's most obvious if I look at something that's a not-too-bright white, such as a piece of paper indirectly lit, and then close first one eye and then the other. The paper which looked neutrally white before looks faintly yellowish to the one eye and faintly bluish to the other.
In the right lighting conditions, it can also make the entire visual field look warmer and/or more vivid to the red-skewed eye and colder and/or slightly washed-out to the blue-skewed eye. I wonder which way 'round the causality works here - it could be that an eye actually perceiving more red than blue tricks the brain into thinking the colours are more vivid because red has the more vivid associations (alarm, blood, fire), or it could be that an eye perceiving more colour across the spectrum tricks the brain into tinging the picture reddish, for some reason.
The former version sounds more plausible to me; if it's the latter, might there be a compensatory better night-vision in the eyes that sees colours less vividly?
