Leucism is a condition in which there is partial loss of pigmentation in an animal resulting in white, pale, or patchy coloration of the skin, hair, feathers, scales or cuticle, but not the eyes. Unlike albinism, it is caused by a reduction in multiple types of pigment, not just melanin.

Something I fail to understand. If albinism only affects melanin, then why do human albinos have trouble with eyesight, which I had assumed to be associated with the loss of one or more retinal pigments?
