Refractive errors in 611 persons living in a rural area were examined. Males numbered 281 and females 330. The age range was from 6 to 85 years. In 73 (11.9%) persons the refraction was myopic (SER less than or equal to 0.5 D) and in 173 (28.3%) hyperopic (SER greater than or equal to + 2 D). Myopia was most frequently detected in persons aged 21-30 years (22.6%), and the proportion of myopia decreased towards both extremes of age. In all age groups females were more myopic than males. In persons aged 21-60 years the most educated proved to have more myopia and less hyperopia than those with less education. In 158 (25.9%) of the eyes, astigmatism was detectable. The degree of astigmatism changed little with advancing age and was independent of sex. In myopic eyes the range of astigmatic error was wider than in hyperopic eyes. The axis of + cylinders was in hyperopic eyes mostly horizontal and in myopic eyes vertical. Anisometropia of 1.25-2.0 D was detected in 24 (4.0%) persons and in 19 (3.1%) persons it was over 2 D.
对居住在农村地区的611人进行了屈光不正检查。其中男性281人，女性330人。年龄范围为6至85岁。73人（11.9%）屈光为近视（等效球镜度小于或等于-0.5D），173人（28.3%）为远视（等效球镜度大于或等于+2D）。近视最常见于21至30岁的人群（22.6%），且近视比例向两个年龄极端方向降低。在所有年龄组中，女性比男性近视程度更高。在21至60岁的人群中，受教育程度最高者比受教育程度较低者近视更多、远视更少。158只眼（25.9%）可检测到散光。散光程度随年龄增长变化不大，且与性别无关。近视眼中散光误差范围比远视眼更宽。远视眼中正柱镜轴主要为水平方向，近视眼中为垂直方向。24人（4.0%）检测到1.25 - 2.0D的屈光参差，19人（3.1%）屈光参差超过2D。
