Apart from the lack of melanin pigment, albinism often brings the shortsightedness, so all the members of Pullan family can’t see properly and are extremely vulnerable to the direct sunlight. Nevertheless, the Pullans enjoy their lives and are looking forward to global recognition as the unique family.
apparently blue eyes first arose about 8,000 years ago in a single individual in what is now the country of rumania. for all the rest of mankind's existence, man had brown eyes, other than perhaps albinos, whose eye color comes from different genetic switches. blue eyes are in effect brown eyes with diluted pigment.
