Summary

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

Detailed description

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.

Conditions

• Visual Fatigue

Interventions

Type	Name	Description
BEHAVIORAL	comfortable reading mode	Subjects are asked to read a terminal display device for 45 minutes, featuring texts with different reading mode treatments. Specifically, they will read the same text content for 45 minutes with different background and text color. The participants will complete a total of 4 sets of tests in a random order.
