Albinos are animals and people with pale skin, eyes, hair, fur, or feathers because they can't make melanin normally (see Eye Colour Facts #1). There are many types of albinism. Most albinos have blue eyes, but some are pink because the iris (the colored part of the eye) has so little color that the blood vessels inside the eye are visible through the pale, white iris.
Besides giving skin, eyes, and hair its color, melanin protects eyes from the sun and albinos are very sensitive to light. But albinism may be linked to other eye abnormalities such as abnormal nerve connections and light receptors, constantly moving eyes, squints, short sightedness and poor vision even with glasses or laser eye surgery.
