What is acromatopsis?

In the atoll of Pingelap, Micronesia, there is a high proportion of cases of achromatopsia in people who see it in black and white. The origin of this was in a typhoon of the eighteenth century; the storm destroyed the population, but a person with acromatopsis survived. There are many of his descendants in Pingelap today who have developed their black and white culture.
