摘要
通过整群抽样并结合医学筛选,以主观测评和客观测量相结合,探索在不同的环境照度下,手机VDT对人体视疲劳主观感受、CFF、视力的影响规律.结果显示,30 min的手机VDT持续干扰,在100 lx、0 lx两种环境照度下,干扰前、后受试者视疲劳主观感受将产生不同程度的不适感.且0 lx环境照度产生的不适感较100 lx的更复杂;CFF值干扰前、后差异不具显著性;左、右眼视力受到短时不同程度的影响.结论:应尽量减少手机的持续作业时间,并合理选择手机作业的环境照度.
By cluster sampling combined with medical screening,with the combination of subjective evaluation and objective measurements,explore the effect of fatigue subjective feelings,CFF and visual acuity mobile phone VDT on human body in different environment illumination. The results show that 30 min mobile phone VDT continuous interference in two kinds of illumination environment as 100 lx and 0 lx,interference before and after the subjects of visual fatigue subjective feelings will produce different degrees of discomfort. Discomfort produced in environmental illumination of 0 lx is more complex than that of 100 lx; CFF interference value before and after the difference is not significant; the left and right eye vision is short-term effect. Conclusion: Continuous operation time of mobile phone should be minimized; and a reasonable environmental illumination for mobile phone operation should be chosen.
