Color blindness often remains undiagnosed in adults

Color blindness can remain undiagnosed for years because individuals born with the condition often do not realize their perception differs from the norm. According to the National Eye Institute (NEI), approximately one in 12 men is affected by some form of color vision deficiency.

The condition involves various alterations in chromatic perception and does not necessarily mean seeing the world in black and white. The most common hereditary forms involve difficulty distinguishing between red and green tones, though less frequent variations related to blue and yellow also exist.

There is a significant prevalence difference between genders due to genetics; the genes for the most common deficiencies are located on the X chromosome. Since men have only one X chromosome, a single alteration can manifest the condition, whereas women typically require alterations on both X chromosomes to be affected.

While hereditary color blindness has no cure, changes in color perception can also occur later in life due to retinal diseases, optic nerve issues, brain areas, or medication use. Specialists recommend immediate medical consultation for sudden changes in color vision.
