Note: Father’s Education Level, 1 = no education, 2 = primary education, 3 = secondary education, 4 = tertiary/diploma education, 5 = tertiary/university education. Visual Acuity for the better eye (VA), 1 = good VA in Grades 3 and 4, 2 = poor VA in Grade 3 and good VA in Grades 4, 3 = good VA in Grade 3 and poor VA in Grades 4, 4 = poor VA in Grades 3 and 4, good VA = less than 0.2, poor VA = greater than 0.2.
CI = Confidence interval.
