Color blindness is a condition characterized by alterations in chromatic perception, most commonly involving difficulty distinguishing between red and green tones. It often remains undiagnosed for many years because individuals may lack a reference point to realize their perception differs from the norm.

Data indicates the condition is significantly more prevalent in men than women due to its genetic link to the X chromosome. While hereditary forms are common, changes in color vision can also be acquired later in life through medication, retinal diseases, or optic nerve issues. Specialists advise seeking medical consultation if sudden changes in color perception occur.
