This study tested the visual comfort and visual fatigue of low blue light condition and the general condition on the same phone under the low illumination environment by critical fusion frequency (CFF), electroencephalogram (EEG) and subjective perception scale of visual fatigue. 17 participates (9 females, 8 males) participated in the experiment, and they were asked to conduct 60 min screen tasks including reading, watching the video and gaming, respectively. Their EEG indicators were recorded in the whole experiment. Before and after the screen tasks, they were measured by critical fusion frequency (CFF) and after the task they were required to finish a subjective perception scale. The result showed that the difference of CFF indicators under different conditions is remarkable, and there was remarkable difference of EEG attention index after completing the screen tasks between the two conditions. As a conclusion, the low blue light condition caused less visual fatigue and high level of attention than the general condition, and CFF and EEG were better indicators for evaluating the visual fatigue and comfort of the different phone screen.
