Abstract
 

Introduction: Near work has always been associated with the influence of myopia (S-M. Saw, et al., 2002; B. Kinge, et al., 2002; I.F. Hepsen, et al., 2001). It has been shown to affect the progression of myopia. In this study, we aimed to determine if there is a relationship between outdoor activities and myopia, as the prevalence of myopia seems to be lower in children who are more active outdoor. (K.A. Rose, et al., 2008). In addition, we also aimed to establish if the level of education affects myopia prevalence. Method: A cohort study was carried out on 16,484 male volunteers, aged between 16 to 21 years old, who are pre-enlistees to the Singapore Armed Forces. A demographic survey was conducted to determine their level of education, type of houses they stay and the daily amount of visual work for near and distance. The refractive status and corneal curvature was measured using the Huvitz NRK-3100 auto-refractor. Results: Pearson's correlation test shown no significant correlation between amount of near work and myopia. However, individuals who are more active outdoors tend to be less myopic (pr=0.147, p<0.01). The analysis indicated that high myopia is associated with higher levels of education (pr=-0.243, p<0.01) and individuals staying in bigger houses (pr=0.121, p<0.01). Individuals with higher levels of education are also more likely to stay in bigger houses (pr=0.259, p<0.01). Conclusion: The trend suggests lower educational background and longer hours spent on outdoor activities are associated with less myopia, but not as a result of near work. This suggest that near work may not necessarily has a high impact on myopia.
