Report on Color Vision Deficiencies.
—This report from the National Center for Health Statistics presents data on the prevalence of color vision deficiencies among youths 12 to 17 years of age in the United States as estimated from the Health Examination Survey of 1966-1970. Comparisons are made with the findings from the 1963-1965 Health Examination Survey among children 6 to 11 years of age in the United States and with those from other recent surveys throughout the world.About 4.1% or an estimated 934,000 US youths 12 to 17 years of age were found to have color vision deficiencies. Boys were about 12 times as likely as girls to have this defect—more than 7.5% of boys showed evidence of a color vision deficiency while only 0.6% of girls were so affected. There were no significant differences in the prevalence rates for white and black boys.Copies of color vision
