Summary
Color blindness (dyschromatopsia) affects nearly 5% of boys, impacting their general school performance. Early preschool screening for this congenital condition is recommended to support learning.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Educational Psychology
Background:
- Dyschromatopsia, a congenital, sex-linked color vision deficiency, affects a significant portion of the male population.
- Assessing the impact of color blindness on academic achievement is crucial for educational support.
Purpose of the Study:
- To investigate the prevalence of dyschromatopsia in junior high school boys in Liguria, Italy.
- To evaluate the relationship between color blindness and school achievement in adolescents.
Main Methods:
- A cohort of 3124 junior high school boys (ages 10-15) was screened for dyschromatopsia using Ishihara and Farnsworth D-15 tests.
- School marks of 82 color-blind (dyschromate) students were compared with those of 82 age- and class-matched color-normal (orthochromate) students.
Main Results:
- The prevalence of dyschromatopsia was found to be 4.87%, slightly below the Italian average.
- Dyschromate students demonstrated significantly lower general school achievement compared to orthochromate peers, with the exception of art subjects.
Conclusions:
- Color blindness is associated with learning difficulties, particularly in subjects where color is a key didactic element.
- Implementing preschool screening for dyschromatopsia could facilitate early intervention and support for affected students.
