| Abstract | Reported were estimates of the uncorrected binocular visual acuity levels of distance and near for children aged 6 to 11 years in the noninstitutional population of the United States in relation to their demographic and socioeconomic background. A sample of 7,119 children participated in the Health Examination Survey program of 1963-65. Findings indicated that the distribution of uncorrected distance and near binocular visual acuity among white and Negro children was similar. The proportion with defective distance acuity of 20/40 or less was found to increase with age among the white but not the Negro children. Additional findings were that children from the South and West had better binocular visual acuity at distance and near than children from the Northeast and Midwest. Also, visual acuity at distance and near tended to be better among white than Negro children in the Northeast and Midwest but the reverse in the South and West. Children living in rural areas were found to have better visual acuity at distance and near than did their peers living in urban communities. The proportion of children with defective distance acuity was found to increase with parental educational level and/or family income. Tables of extensive statistical data were included in the report.
