Studies of birth month confirm the role of education in myopia development: A review

The association of education and myopia has been long known. Only recently has causality been established wherein more time spent in education leads to more myopia. A series of five studies conducted in China and published in the last 3 years have demonstrated a consistent link between birth month and myopia. Given the regulated age of school entry in China, the collective agreement of these papers provides compelling evidence that the schooling environment rather than age per se is the key element driving myopia onset and degree.
