Summary

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.

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 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.

Conditions

• Visual Fatigue
• Dry Eye

Interventions

Type	Name	Description
BEHAVIORAL	color temperature change mode	Subjects are asked to read a terminal display device for 50 minutes, featuring texts with different color temperature mode treatments. Specifically, they will read the same text content for 50 minutes with different color temperature mode. The participants will complete a total of 2 sets of tests in a random order.
