Achromatopsia

Color vision disorder When I was young, "color vision abnormality" was said that this person does not mean to see the world like an old movie, but can not distinguish between green and red. I think this understanding is very advanced and I will immediately share my knowledge with people I do not know about it. After investigating this, I refused this generalization and in the alternative had to support a wide range of diseases. And led to different types of colors perceived in a "normal" way.

Rods are usually monochrome, called full-color blinds, because the retina does not contain pyramidal cells, so that in addition to no color distinction, vision is difficult under normal intensity light. It is usually rare, but Pingelap island is very colorful. Pingereap island is a part of the Federated States of Micronesia and is called Maskon. About 10% of the population owns it. % Is an unaffected carrier. The island was damaged by a storm of the 18th century (an example of a genetic bottleneck), and one of several male survivors had a full-color blind gene. Before foreign troops brought illness to the island in the 1940 's, the population increased to thousands.

It was in December, and the 34 - year - old Harbison was wearing a zippered gray shirt under narrow gray trousers and a black jacket. Born in Belfast, he grew up in Spain and suffered from a rare illness called full color blindness, but he could not find the color. His antenna ended in the form of a fiber optic sensor hovering just above the eyes, which changed it. But he is very interested in how color looks. After training as a musician, he tried to find colors in his voice in his teens. After some low tech errors began, in his twenties he found a surgeon trying to plant that device (he is still anonymous).

Full color blindness is relatively rare as a color selective visual disorder, and Sacks (1995a) describes the artist's experience of full color blindness after traumatic brain injury. Discontinuous brain injury was not found, but he selectively lost color perception. Something seemed to be "gray" for him. After the accident, the artist could not imagine color, his dreams and migraine without color. Before this, his paintings were very abstract and colorful. After the accident, he drew a figurative and abstract image. The color he first used was chaos, and he eventually made black and white paint by himself. Though they do not have color, his painting shows an important retention of shape, contrast and composition. After all, he reintroduced color into his painting, but he used a very limited palette.
