Li M, Lanca C, Tan CS, et al. - In the present study, the researchers sought to assess the correlation of reported time outdoors and light exposure patterns with myopia among children aged 9 years from the Growing Up in Singapore Towards Healthy Outcomes birth cohort. They evaluated reported time outdoors (min/day), light exposure patterns and outdoor activities of children aged 9 years (n = 483) with a questionnaire, the FitSight watch and a 7-day activity diary. Four hundred eighty-three (966 eyes) multiethnic children (50.0% boys, 59.8% Chinese, 42.2% myopic) were involved. Among Singaporean children aged 9 years, reported time outdoors, light levels and number of light exposure episodes were low. Reported time outdoors was found to be protective against myopia, but not light levels or specific light measures. A multipronged approach to increase time outdoors is suggested in the combat against the myopia epidemic.
