In just about Scandinavian countries, however, it is difficult to tell if a child has albinism because fair hair and eyes are the norm. A common fable is that by definition people with albinism consider red eyes. In fact at that place are different types of albinism, and the amount of pigment in the eyes varies.The National plaque for Albinism and Hypop igmentation dispels many myths and legends in popular culture, Although most individuals with albinism wear reddish or purplish eyes, most have blue eyes. s brightenly have hazel or chocolate-brown eyes.People with albinism always have problems with day-dream, and many have low deal.

Later researchers used a test that involved plucking a hair root, and seeing if it would make pigment in a test tube. This test disordered ty-neg (no pigment) from ty-pos (some pigment). Further research showed that this test was inconsistent, and added little information to the clinical exam.
