本文从1982～1983年对不同职业、身体健康、外眼及内眼未见异常改变的40～50岁男、女4950人(9900眼)进行了远视力及近视力的调查。结果表明,远视力正常近视力不正常眼的百分率随年龄增长而逐渐上升。平均发生年龄为45.41岁,较以前文献报告迟发生5年,可能与健康状况好转有关。在此组人群中,近视力不正常眼占54.29%,因此提示对这组人群中近视力的矫正非常重要。通过矫正可以补偿调节力的不足,减少视力疲劳,使之得到较长时间近距离工作的最大适应性。现将调查情况报告如下。
This article from 1982 to 1983 for different occupations, good health, no change in the outer eye and the inner eye abnormalities in 40 to 50-year-old male and female 4950 (9900 eyes) were investigated for far vision and near vision. The results showed that the percentage of patients with normal far-sighted and near-vision abnormal eyes gradually increased with age. The average age at birth was 45.41 years, which was five years later than reported in previous literature and may be related to the improvement of health status. In this group of people, myopic eyes accounted for 54.29% of abnormal eyes, suggesting that this group of people in the correction of near vision is very important. Correction can compensate for the lack of regulation force, reduce visual fatigue, so that the work of a long time close to the maximum adaptability. Now the investigation report as follows.
