I'm not an equine expert by any stretch of the imagination but as a nurse perhaps I could offer a bit of information that might relate to horses just as well as people. The blue color is equilivent to the green/blue/brown of our eyes and it has no relation to how light enters the pupils and is reflected on the retina, which is how the cones and rods (which "see" color in our eyes) recieve the optical neural stimulation and relay the impulses into "seeing" in black and white or color in people. I don't know if horses see in color( I don't think they do) but the number of rods in horses is greater than ours so their ability to see in dimmer light is much greater than ours... therefor... the blue eyed equine should be able to see as well as the brown eyed one! Any one out there please correct me if I'm wrong.

I am quite sure that horse's see in colour as we have a horse that we have proven is colour blind where the other's can see the colour's no problems.
But as to the pigmentation of the eye, it does not seem to have any impact even in horses that have one blue and one brown eye.
