Color vision deficiency affects 8% of men and 3% of women. This study on color blindness found no significant differences based on sex or race in a diverse adult sample.

Area of Science:

  • Ophthalmology
  • Human Genetics
  • Visual Science

Background:

  • Color vision deficiency (CVD) affects a significant portion of the population, impacting daily life and certain professions.
  • Prevalence rates of CVD can vary across different demographic groups, necessitating accurate population-based studies.
  • Understanding the genetic and demographic factors influencing CVD is crucial for early detection and intervention.

Purpose of the Study:

  • To determine the incidence of color vision deficiency in a representative adult sample.
  • To investigate potential variations in CVD prevalence based on sex and race.
  • To evaluate the efficacy of Pseudo-Isochromatic Plates in assessing color vision across diverse groups.

Main Methods:

  • Utilized Pseudo-Isochromatic Plates (PIPs) for color vision testing.

  • Recruited a sample of 112 adults aged 20-80 years.
  • Collected demographic data including sex (53% women) and race (12% minorities).

    • Main Results:

    • Overall color vision deficiency prevalence was observed.
    • 8% of men and 3% of women were identified as color deficient.
    • No statistically significant differences in CVD prevalence were found between sexes or racial groups.
    • Nearly half of the PIPs used were found to be non-discriminatory across tested demographic groups.
    • Color preferences in the normal vision group showed a strong preference for blue, with no sex-based differences.

    Conclusions:

    • The study provides incidence data for color vision deficiency in the tested adult population.
    • Sex and race did not appear to be significant factors in the overall prevalence of color vision deficiency within this sample.
    • The effectiveness of certain Pseudo-Isochromatic Plates in differentiating color vision status across demographic groups warrants further investigation.
