摘要
本文观察了40名电子计算机操作人员的视疲劳和作业能力、发现眼胀、眼痛、视物模糊、颈痛、肩痛、背痛、腰痛、记忆力下降、乏力、头痛、头昏、失眠、月经不调等均高于对照组;还发现有显著的视疲劳与作业能力下降。其原因可能是综合因素联合作用的结果,包括空气中负离子浓度低、视觉高度紧张、长时间过度注视荧光屏、不适当的工作体位和精神紧张因素等。
This paper reports the results of a survey of the visual fatigue and work capacity of 40 video display terminal (VDT)operators.The frequencies of distension of the eye- ball,ophthalmidynia,blurring of vision,pain in the neck,pain in the shoulder,backa- che,lumbago,bad memory,fatigue headache,vertigo,insomnia,and irregular,mens- truation were significantly higher in the test group than in the control group.Visual fatigue and the reduction of work capacity appeared also.These phenomena may be due to the combined effects of factors such as less anions in the air,continuous visual strain, long periodsof looking at the fluorescent screen,improper working posture,and stresses at work.
