Achromatopy

Achromatopia (also achromatopsia) is a rare congenital anomaly of color vision, in which the set of colors observed by a person does not correspond to the normal appearance. The anomaly manifests itself precisely in the ability to normally distinguish colors, however, in people with this feature, the perception of shades and tones of other color spectrums remains normal.

The term "achromatopia" was coined on August 3, 1892 by the English scientist and physician Aylmer Veit (June 28, 1849 - January 30, 1917) in his work The Acromatopsia of the Nightingale's

Achromatopy or achromopsia in ophthalmology is a color vision disorder in which one or more colors are no longer recognized by the visible outer parts of the retina or the nervous tissue of the brain for accurate transmission to the visual centers. It is divided into several types, based on the damaged color class - the patient: Aggregate when the cones of red, green, blue and light sensitivity are damaged simultaneously; Monochrome – loss of color of one color sensitivity - additive (trichromasia): blue, green or red; Dichromatic with cone damage

**Achromatopy** (ancient Greek ἀχρωτοσύνη - colorless, from ὅρος achron - without color and ‑sune - property), or “amblyopic color blindness” - a rare congenital defect of color vision, a type of color blindness, characterized by the inability to distinguish differences between shades colors due to the complete mismatch of cone receptors that respond to a certain color-perceptible range of wavelengths to photons. People with achromatopsia lack two types of cones: cones that are sensitive to the red and green spectrum of light, or cones that are sensitive to the blue and some of the red spectrum. Also, color blindness is associated with a pathological change in the structure or functioning of neurons in the visual system responsible for encoding and transmitting color information at the retinal level of 57 chromosomes. As a result, patients perceive light as having a cold or warm tint. Most carriers of this abnormal genetic defect have a normal mentality, the ability to
