简要总结
The purpose of this study was to investigate the effects of visual fatigue and dry eye level under different correlated color temperature modes, and to evaluate the effect of new designed dynamic color temperature change modes on the improvement of visual fatigue and dry eye level.
详细描述
The effect of electronic display devices on visual fatigue of human eyes was the primary evaluation index and the primary outcome index of this experiment. Secondary outcome indicators were tear film break-up time, tear lipid analysis, conjunctival congestion score and subjective visual fatigue score. Other outcome indicators were eyeblink detection, accommodative function and Schirmer test. Baseline values of the above metrics were measured separately before each group of trials and then, after 50 minutes of e-text reading, specific values of the different metrics were collected when using different color temperature modes and all valid measurements were statistically compared and analysed. To assess the effect of new designed dynamic color temperature change modes on reducing visual fatigue and dry eye symptoms.

研究组 & 干预措施
gradient change group
This is the group that performs visual evoked tasks using dynamic color temperature change mode 2 which changes from 6500K to 4000K. In this group, the impact of the same text content on the visual fatigue and comphrehensive analysis of tear film were assessed, including but not limited to indicators such as blinking detection, visual function and so on.
干预措施: color temperature change mode (Behavioral)
6500K group
This is the group that performs visual evoked tasks using conventional color temperature mode of whose vaule is 6500K. In this group, the impact of the same text content on the visual fatigue and comphrehensive analysis of tear film were assessed, including but not limited to indicators such as blinking detection, visual function and so on.
sigmoid change group
This is the group that performs visual evoked tasks using dynamic color temperature change mode 1 which changes from 6500K to 4000K. In this group, the impact of the same text content on the visual fatigue and comphrehensive analysis of tear film were assessed, including but not limited to indicators such as blinking detection, visual function and so on.

结局指标
主要结局
Critical flicker fusion frequency
时间窗: Participants underwent three randomized experimental conditions through study completion, an average of 1 months. For each condition, CFF test was administered at baseline (pre-experiment) and post-task,totaling six completions per participant.
Critical flicker fusion frequency was measured before and after the task by a flicker fusion frequency detection device to assess changes in the degree of ocular fatigue. To compare the difference in CFF after wearing anti-blue glasses with normal glasses and to evaluate the effect of anti-blue glasses in preventing asthenopia.
