Abstract:Objective: To investigate the impact of near vision behavior on myopia progression in schoolchildren. Methods: This was a prospective study. The subjects were recruited from the Eye Hospital, Wenzhou Medical University during 2014-2015. One hundred and twenty-one myopia children (7-12 years) were enrolled and randomized into two groups: single vision lenses group and +2.00 D progressive addition lenses group. Spherical equivalent was measured at baseline and 6-month intervals for 2 years. Near vision behavior parameters were measured with a Polhemus Fastrack system. The right eye data of the subject was taken for statistical analysis. Generalized estimating equation was used to compare the changes in near vision behavior. Pearson correlation test and linear regression were used to analyze the relationship between near vision behavior and myopia progression. Results: There were no significant differences in spherical equivalent and near vision behavior parameters between single vision lenses group and progressive addition group. The baseline reading and writing distances were 31.8±5.8 cm and 25.2±5.8 cm, respectively. Writing distance at baseline were associated with myopia progression -1.54±0.60 D (r=-0.25, P=0.014). There was a correlation between writing distance of less than 20 cm and myopia progression (r=-0.52, P=0.011). There was a difference in myopia progression between writing distance less than 20 cm and writing distance greater than 30 cm (F=3.86, P=0.020). Conclusions: Closer working distance was correlated with greater myopia progression. Appropriate near-vision behavior was one of the essential strategies for myopia prevention and control in children.
