The examinations have been carried out under model conditions in women aged 33.6 +/- 3.8, in whom refraction defects or other sight organ disorders had been excluded. In order to select factors that would be most sensitive and specific for evaluation of visual fatigue, variations in the following indices of the sight organ occupational condition have been analysed: the near vision point, dispersing lens tolerance, retina sensibility, critical fusion frequency, speed and accuracy of perception, visual simple and choice reaction time. The indices have been analysed under the performance of sigh work and medium-hard physical effort. Variations in the near point and retina irritability have been regarded the most sensitive and specific indices of asthenopia. In addition, intra- and interpersonal variability, as well as seasonal variability of the indices listed have been assessed. Significant seasonal differences have been found between the values measured in the persons prior to work in summer and winter for near vision sense point, dispersing lens tolerance, retina irritability, and critical fusion frequency.
这些检查是在33.6±3.8岁的女性中按照标准条件进行的，这些女性已排除屈光缺陷或其他视觉器官疾病。为了选择对评估视觉疲劳最敏感和特异的因素，分析了视觉器官职业状况的以下指标变化：近视点、散光镜片耐受性、视网膜敏感性、临界融合频率、感知速度和准确性、视觉简单反应时间和选择反应时间。这些指标是在视力工作和中等强度体力劳动期间进行分析的。近点和视网膜兴奋性的变化被认为是视疲劳最敏感和特异的指标。此外，还评估了所列指标的个体内和个体间变异性以及季节性变异性。在夏季和冬季工作前测量的近视力点、散光镜片耐受性、视网膜兴奋性和临界融合频率的值之间发现了显著的季节性差异。
