Vocabulary of the Color blind
Achromatopsia: Extreme color blindness where a person sees in monochromatic vision, or in complete black and white. This is also known as monochromacy ("Types of Colour Blindness").
Color Spectrum (Visible Spectrum): This is described as the light that the human eye is able to detect. Certain wavelengths create certain colors when seen by the human eye, and this is known as the color spectrum ("What Wavelength Goes With a Color?").
Cones (Cone Cells): Nerve cells inside of the retina of the eye. These allow our eyes to see colors. Color blindness can be caused when something is wrong with these cells ("Color Blindness").
Lazy Eye: A condition where a person lacks the muscles to hold up their eye normally. This is very common in people with achromatopsia ("Color Blindness").

Nystagmus: A condition where a person's eyes may tend rapidly move from side to side. This is associated with color achromatopsia ("Color Blindness").
Retina: A sensitive layer within eye tissues that lines the back of the eye ("Color Blindness").
Trichromacy: Normal vision using all three cones of color: blue, red, and green. People with this type of vision are known as trichromats ("Types of Colour Blindness").
X Chromosome: One of the genes in the human cell. Part of the 23rd pair of sex chromosomes. Females have two X chromosomes, while men only have one ("Inherited Colour Vision Deficiency").
Y Chromosome: One of the two types of genes in the human cell. Part of the 23rd pair of the sex chromosomes. Males have one Y chromosome, while women do not have any (Inherited Colour Vision Deficiency").
