简要总结
The purpose of this study was to investigate the effects of visual fatigue and dry eye level under different reading background polarities and different text colours, and to evaluate the effect of comfortable reading mode 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 film height, and subjective visual fatigue score. Other outcome indicators were blink detection, ocular axial length measurement, accommodative function and retinal fundus blood flow. Baseline values of the above metrics were measured separately before each group of trials and then, after 45 minutes of e-text reading, specific values of the different metrics were collected when using different reading modes and all valid measurements were statistically compared and analysed. To assess the effect of comfortable reading modes on reducing visual fatigue and dry eye symptoms.

研究组 & 干预措施
yellow background and black text mode 1 Group
This is the group that performs visual evoked tasks using yellow background and black text mode 1. In this group, the impact of the same text content on the visual fatigue, and tear break-up time were assessed, including but not limited to indicators such as reading efficiency, blinking detection, visual function and retinal fundus blood flow.
干预措施: comfortable reading mode (Behavioral)
yellow background and black text mode 2 Group
This is the group that performs visual evoked tasks using yellow background and black text mode 2. In this group, the impact of the same text content on the visual fatigue, and tear break-up time were assessed, including but not limited to indicators such as reading efficiency, blinking detection, visual function and retinal fundus blood flow.
干预措施: comfortable reading mode (Behavioral)
black background and white text mode Group
This is the group that performs visual evoked tasks using black background and white text mode. In this group, the impact of the same text content on the visual fatigue, and tear break-up time were assessed, including but not limited to indicators such as reading efficiency, blinking detection, visual function and retinal fundus blood flow.

结局指标
主要结局
Critical flicker fusion frequency
时间窗: Participants underwent five randomized experimental conditions through study completion, an average of 2 months. For each condition, CFF test was administered at baseline (pre-experiment) and post-task,totaling ten 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.
