摘要

Lunn和Banks(1986)研究了视频文本显示用户“视觉疲劳”的原因，发现从视频显示中读取会导致与文本行具有相同空间频率的正弦光栅的对比度阈值提高十倍。他们认为，这可能会导致“视觉疲劳”，可能是由于影响了调节，但他们没有解释为什么印刷文本没有同样的效果。

Reading and Contrast Adaptation

Lunn and Banks (1986), studying the reasons for “visual fatigue” among users of video text displays, found that reading from a video display caused a tenfold elevation of the contrast threshold for a sinusoidal grating with the same spatial frequency as the lines of text. They suggested that this may contribute to “visual fatigue,” possibly by affecting accommodation, but they did not explain why printed text would not have the same effect.
