To the Editor: Nearsightedness is the leading cause of visual impairment in developed countries, present in 30.4 million adults in the United States alone.1 The increasing prevalence of myopia, especially among urban Asian children,2 suggests that early lifestyle factors may play a role. Early visual experiences affect the growth of the eye,3 and nutritionally mediated deficiencies in retinal or visual development in infancy may predispose to myopia. We therefore studied the association of breastfeeding with myopia in Asian school children by using the population in the Singapore Cohort Study of the Risk Factors for Myopia.
