Notes: Data source, baseline survey and evaluation survey; This table shows the results of descriptive statistics on vision knowledge, eyeglasses usage and eyeglasses compliance; Columns (1)–(4) of Panel A shows Vision Knowledge Correct Score in different groups. Knowledge about myopia represents the correct scores for four questions of knowledge about myopia, knowledge about eyeglasses importance represents the correct scores for four questions of knowledge about eyeglasses, and vision knowledge is the sum of the correct scores of knowledge about myopia and knowledge about eyeglasses importance; Columns (1)–(4) of Panel A shows the mean value (standard deviation) of the three variable; Columns (1)–(4) of Panel B shows the number and percentage of eyeglasses usage and eyeglasses compliance in different groups.
