    Abstract

    Distant vision screenings of a national sample of children were performed at the ages of 7, 11, and 16. Many children with normal vision at one screening showed defects at later screenings, and altogether 18% of children with normal vision at the age of 7 had defects by the time they were 16. Twelve per cent of those with normal vision at 7 and 11 had developed a visual defect by the age of 16. Apparent improvements between screenings probably resulted largely from technical difficulties inherent in testing young children. The results clearly indicate the importance of regular vision screening during the school years and the need for comprehensive but flexible back-up services.
