General vision information for teachers

Eighty Percent of what a child learns is acquired through the visual system. Perceptual, learning and behavioural problems are often traced to vision problems. Such problems may also create barriers to childhood play and social development. It is extremely important that vision problems be detected as early in a child’s school career as possible.

Vision screenings performed in the school are not eye exams and can miss serious vision problems. The following check-list will assist classroom teachers and aides in identifying those children in their care who have vision problems. Teachers should encourage parents to have their child’s eyes and visual system examined by an optometrist.
