Re: color perception differences between eyes (was Monitor brightness setting)

I too noticed slight differences in my color perception between my right and 
left eyes years back, particularly when looking at 35mm slides through a loupe 
held up to each eye.  A bit frustrating at the time, as I was a scanner 
operator trying to make fine adjustment to match the original, but could get 
contrary "opinions" from  either eye (not too mention that the brand of loupe 
actually made a difference as well). I brought this up with coworkers and most 
people I worked with had similar disparities between eyes..

 I actually think this is very common as the macula of one eye could be 
slightly denser than the other, or one macula slightly "yellower" in 
pigmentation than the other.

For this reason, I still recommend that samples be swapped from right to left 
and back again when viewing two hard copy samples side by side. It can make a 
difference.  

More profound is that if there exists differences in macular 
density/pigmentation between the eyes in our head, the differences between 
people must be greater.
