屈光不正是一种非常常见的眼部疾病，使眼睛无法对外界物体清晰地聚焦，而导致视力模糊，严重的时候可以引起视力损害。
It occurs when the eye cannot clearly focus the images from the outside world. The result of refractive errors is blurred vision, which is sometimes so severe that it causes visual impairment.

未经矫正的屈光不正(近视、远视或散光)，43%。
Uncorrected refractive errors (myopia, hyperopia or astigmatism), 43 %.
