Daltonism意思

Daltonism is a term that refers to a type of color blindness, specifically red-green color blindness. It is named after John Dalton, an English chemist and physicist who was one of the first people to describe the condition in detail. People with Daltonism have difficulty distinguishing between colors in the red and green spectrums, and they may see these colors as shades of gray or as different colors than what people with normal color vision see.
