Color vision deficiency impacts academic performance, with affected students facing challenges in theoretical subjects but not art. Early identification of color vision issues in youth is crucial.
Area of Science:
- Ophthalmology
- Educational Psychology
- Human Vision
Background:
- Color vision deficiency (CVD) affects a significant portion of the population.
- The impact of CVD on academic achievement is not fully understood.
- Early identification of CVD is important for educational support.
Purpose of the Study:
- To investigate the relationship between color blindness and school achievement in high school students.
- To determine if students with CVD face academic disadvantages in specific subject areas.
Main Methods:
- Administered Ishihara and Farnsworth tests to 3,565 high school art students.
- Compared academic performance in theoretical and art-related subjects between color defective and orthochromate students.
Main Results:
- Color defective students showed discrimination in theoretical subjects compared to orthochromate students.
- No significant difference in performance was observed in art-related subjects.
- This suggests a subject-specific impact of color vision deficiency.
Conclusions:
- Color vision deficiency can negatively affect academic achievement in non-artistic subjects.
- Early detection of color vision issues in students is essential for providing appropriate support.
- Educational strategies may need to account for the challenges faced by students with CVD.
