Factors Contributing to Children’s Myopia: Studies Disclose the Misconceptions

According to the findings of 4 studies, there are a number of factors associated with the onset of myopia. Heredity or a family history of myopia is the strongest factor associated with myopia among young children and adolescents. Less outdoor activity is the second most important factor associated with myopia among children. The degree of association is even stronger than near work. Near work is also associated with myopia in a moderate way, especially children who read and write more than 2 hours/a day and also work more than 0.8 hours/a day on a computer. Watching TV is not associated with myopia even for children who watch more than 2 hours a day.
