In the late eighteenth century a catastrophic typhoon swept over Pingelap, a tiny atoll in the Pacific Ocean. One of the survivors, the king, carried the rare achromatopsia-gen that causes complete colorblindness. The king went on to have many children and as time passed by, the hereditary condition affected the isolated community and most islanders started seeing the world in black and white.Achromatopsia is characterized by extreme light sensitivity, poor vision, and the complete inability to distinguish colors. In Micronesia achromats adapt to their reduced level of visual functioning (due lack of recourses like sunglasses and tinted lenses) by using visual strategies such as blinking, squinting, shielding their eyes, or positioning themselves in relation to light sources.
