1. daltonism

   Congenital red–green color blindness is an inherited condition that is the root cause of the majority of cases of color blindness. It has no significant symptoms aside from its minor to moderate effect on color vision. It is caused by variation in the functionality of the red and/or green opsin proteins, which are the photosensitive pigment in the cone cells of the retina, which mediate color vision. Males are more likely to inherit red–green color blindness than females, because the genes for the relevant opsins are on the X chromosome. Screening for congenital red–green color blindness is typically performed with the Ishihara or similar color vision test. There is no cure for color blindness.This form of colorblindness is sometimes referred to historically as daltonism after John Dalton, who had congenital red–green color blindness and was the first to scientifically study it. In other languages, daltonism is still used to describe red–green color blindness, but may also refer colloquially to color blindness in general.

   Daltonism, also known as color blindness, is a genetic condition that impairs the ability to perceive or differentiate between certain colors. This condition is named after John Dalton, a British chemist and physicist, who was the first scientist to study color blindness after realizing he was affected by it. The most common form is red-green color blindness, followed by blue-yellow color blindness and total color blindness.
