应用视力负荷试验法对266名体格检查合格的学员进行了试验检查。结果,在532只眼中,负荷试验后视力提高97眼,无一眼为近视型屈光。而在负荷试验后视力下降的274眼中,近视型屈光153眼,占视力下降的55.8％,占近视型屈光眼的88.9％.认为视力负荷试验方法简单实用。能对视力状态进行定性分析,可作为视力或屈光边缘眼的补充筛选方法。
The visual acuity test was used to test 266 qualified medical students. As a result, in 532 eyes, visual acuity improved 97 eyes after the load test, none of which was myopic refractive. In 274 eyes with decreased visual acuity after stress test, myopia-type refraction was 153 eyes, accounting for 55.8% of vision loss, accounting for 88.9% of myopia-type refraction eyes.It is considered that visual acuity test method is simple and practical. Qualitative analysis of visual acuity can be used as a supplementary screening method for visual acuity or refractive edge of the eye.
