Convergence Insufficiency Symptom Survey scores for required reading versus leisure reading in school-age children

Convergence Insufficiency Symptom Survey scores vary greatly depending on the type of near activity being surveyed and thus do not accurately isolate and reflect near visual ability. Beginning each survey with the question about self-rated reading speed could eliminate the need for additional questions if a child self-rates his or her reading speed as average or better. Because of the influence of the type of near visual activity on symptoms, survey questions should explicitly specify the near visual activity to prevent a child's interpretation of the question's intent from affecting the symptom score.
