Outdoor Activity During Class Recess Reduces Myopia Onset and Progression in School Children

  • The aim of this study was to investigate the effect of outdoor activity during class recess on myopia changes among elementary school students in a suburban area of Taiwan.

  • Elementary school students 7 to 11 years of age recruited from 2 nearby schools located in a suburban area of southern Taiwan. The children of one school participated in the interventions, whereas those from the other school served as the control group.

  • The interventions consisted of performing a recess outside the classroom (ROC) program that encouraged children to go outside for outdoor activities during recess. The control school did not have any special programs during recess.

  • Data were obtained by means of a parent questionnaire and ocular evaluations that included axial length and cycloplegic autorefraction at the beginning and after 1 year.

  • The study concluded that outdoor activities during class recess in school have a significant effect on myopia onset and myopic shift. Such activities have a prominent effect on the control of myopia shift, especially in nonmyopic children.
