Intermittent Illumination from Visual Display Units and Fluorescent Lighting Affects Movements of the Eyes Across Text
研究发现，荧光灯和阴极射线管屏幕的间歇照明会放大眼睛在文本上的扫视幅度，幅度约等于一个字母宽度，这可能解释了为什么在电脑屏幕上阅读比纸质阅读慢。
The size of eye movements across text was measured under conditions in which the text was illuminated by fluorescent light or was displayed on the screen of a cathode-ray tube. Under these conditions of intermittent illumination the high-velocity saccadic eye movements were enlarged. The extent to which they were enlarged depended on the frequency of intermittency, but was generally equivalent to the width of one letter. This disturbance of ocular motor control by intermittent illumination might help to explain why reading is generally slower on computer display terminals than with printed text.
