Abstract

The Authors studied the relationship between visual fatigue (or asthenopia) and different types of work with display units on about 30,000 videoterminal (VDT) operators of the Italian telecommunication company. Visual fatigue was reported with data entry, data checking, word processing, dialogue enquiry, and various services. The Chi-square test showed that asthenopia was not related to any particular type of VDT work, comparing subjects working at the VDT for similar times each week. These findings provide further confirmation that the main factor determining visual fatigue in VDT operators is the amount of time spent at the display units.

摘要

作者对意大利电信公司约30000名视频终端（VDT）操作员进行了研究，探讨视觉疲劳（或眼疲劳）与不同类型的显示单元工作之间的关系。数据录入、数据核对、文字处理、对话查询及各种服务工作均报告有视觉疲劳。卡方检验表明，对于每周在VDT上工作时间相似的受试者，眼疲劳与任何特定类型的VDT工作均无关联。这些发现进一步证实，决定VDT操作员视觉疲劳的主要因素是在显示单元上花费的时间量。
