People with albinism often have poor vision. A new study from the Netherlands Institute for Neuroscience reveals the underlying cause. In Europe, albinism occurs in 1 in 20,000 individuals. However, in some populations, it is much more common, affecting 1 in 1,000 people. People with albinism lack pigment and frequently have poor eyesight. For example, they may see at a distance of 20 meters what someone with pigment sees at 80 meters. But what exactly causes this? One of the causes is the spontaneous back-and-forth movement of the eye, called 'pendular nystagmus.
