What was done
A narrative review synthesizing literature from peer-reviewed articles and large-scale epidemiological studies identified via database searches on color vision deficiency (CVD) prevalence, awareness, diagnosis, and lived experiences.
What was found
Red-green CVD affects up to 8% of males and 0.5% of females of Northern European descent, with lower rates reported in Asian and African populations. The abstract reports that although CVD is largely congenital, diagnosis is frequently delayed until school age, adolescence, or adulthood due to limited routine screening. No further numerical findings are provided in the abstract.
Why it matters
It highlights that color vision deficiency remains underdiagnosed in early childhood, pointing to the need for routine screening, classroom adaptations, and occupational guidance.
Limits
This is a narrative review without systematic search protocols, risk-of-bias assessments, or quantitative data synthesis. The abstract omits the number of reviewed studies and specific prevalence statistics for Asian and African populations.
