众多的流行病学调查和动物实验表明,精细作业的“近长因素”是导致近视的重要因素。为此,对丝毯厂剪花、织造的103名精细作业女工进行了远近视力、主觉验光和业余近视因素等方面的调查,试图对其视力下降规律及其影响因素作一初步探讨。 调查方法 (一)裸眼远近视力检查 采用照度为500～700Lux的人工照明国际视力表,按标准要求进行检查。 (二)主觉验光 按标准要求进行。对远视力≤1.0、近视力≥0.9者使用凹凸透镜片插片验光。
Numerous epidemiological investigations and animal experiments show that the “near-long-term factor” of fine work is an important factor that causes myopia. To this end, the silk carpet factory cut flowers, weaving of 103 fine work women were far and near vision, the main optometry and amateurism myopia and other aspects of the survey, attempting to assess their rules of vision and its influencing factors for a preliminary study. Survey methods (A) naked eye near vision test using illumination of 500 ~ 700Lux artificial lighting International Visual List, according to standard requirements for inspection. (B) the main optometry according to the standard requirements. For distance vision ≤ 1.0, near vision ≥ 0.9, the use of concave and convex lens sheet optometry.
