Doug, I think that you and I have had this discussion in the past but I think it's worth repeating for other folks. The eye pupils only appear black They are not black because of melanin. I'll just quote the wiki article here and leave it at that.

"The pupil is a hole located in the center of the iris of the eye that allows light to enter the retina. It appears black because most of the light entering the pupil is absorbed by the tissues inside the eye."

Note that it says, "appears black."

In a simple explanation, with albinism, the pupil appears pink because the lack of coloring in the iris allows light to escape and thereby shows the red of the blood in the eye.

I rarely interject but every so often and feel a need to add a point.
