1. Color blindness

   Color blindness or color vision deficiency (CVD) is the decreased ability to see color or differences in color. It can impair tasks such as selecting ripe fruit, choosing clothing, and reading traffic lights. Color blindness may make some academic activities more difficult. However, issues are generally minor, and the colorblind automatically develop adaptations and coping mechanisms. People with total color blindness (achromatopsia) may also be uncomfortable in bright environments and have decreased visual acuity. The most common cause of color blindness is an inherited problem or variation in the functionality of one or more of the three classes of cone cells in the retina, which mediate color vision. The most common form is caused by a genetic disorder called congenital red–green color blindness. Males are more likely to be color blind than females, because the genes responsible for the most common forms of color blindness are on the X chromosome. Non-color-blind females can carry genes for color blindness and pass them on to their children. Color blindness can also result from physical or chemical damage to the eye, the optic nerve, or parts of the brain. Screening for color blindness is typically done with the Ishihara color test.There is no cure for color blindness. Diagnosis may allow an individual, or their parents/teachers to actively accommodate the condition. Special lenses such as EnChroma glasses or X-chrom contact lenses may help people with red–green color blindness at some color tasks, but they do not grant the wearer "normal color vision". Mobile apps can help people identify colors.Red–green color blindness is the most common form, followed by blue–yellow color blindness and total color blindness. Red–green color blindness affects up to 1 in 12 males (8%) and 1 in 200 females (0.5%). The ability to see color also decreases in old age. In certain countries, color blindness may make people ineligible for certain jobs, such as those of aircraft pilots, train drivers, crane operators, and people in the armed forces. The effect of color blindness on artistic ability is controversial, but a number of famous artists are believed to have been color blind.

1. color blindness

   Color blindness is a visual deficiency or condition where an individual's perception of color is different from normal due to the inability of certain retinal cells to correctly identify and respond to variations in wavelengths of light. This condition may prevent one from distinguishing certain colors, most commonly red and green, or in rare cases, blue and yellow. Some individuals may not see colors at all, a condition known as achromatopsia. Color blindness is often inherited, but can also result from physical or chemical damage to the eye, the optic nerve, or parts of the brain that process color information.

1. Color blindness

   Color blindness, or color vision deficiency, is the inability or decreased ability to see color, or perceive color differences, under normal lighting conditions. Color blindness affects a significant percentage of the population. There is no actual blindness but there is a deficiency of color vision. The most usual cause is a fault in the development of one or more sets of retinal cones that perceive color in light and transmit that information to the optic nerve. This type of color blindness is usually a sex-linked condition. The genes that produce photopigments are carried on the X chromosome; if some of these genes are missing or damaged, color blindness will be expressed in males with a higher probability than in females because males only have one X chromosome. Color blindness can also be produced by physical or chemical damage to the eye, the optic nerve, or parts of the brain. For example, people with achromatopsia suffer from a completely different disorder, but are nevertheless unable to see colors. The English chemist John Dalton published the first scientific paper on this subject in 1798, "Extraordinary facts relating to the vision of colours", after the realization of his own color blindness. Because of Dalton's work, the general condition has been called daltonism, although in English this term is now used more narrowly for deuteranopia alone.

Examples of color blindness in a Sentence

1. Bob Forrester:

   Here you have a young man who volunteers to go to war to help preserve the United States and United States opportunities, at the same time, he thinks he’s going to be a pilot but has the bad luck of not being a pilot because of his blue eyes, or his color blindness. Which also happened to be one of the things that got him such good movie roles, aside from being a great actor, of course. But it was his experience out there that made him realize the difference between people was circumstance.

2. Jonathan Turley:

   The Court’s argument [Monday] showed that it is high time to return to the constitutional norm of color blindness.
