Study on Changes of Visual Function Before and After 24 hours Simulated Flight Visual Fatigue Protection

To evaluate the effect of visual fatigue protection measures on the relief of visual fatigue caused by 24-h simulated flight. Methods: 6 healthy subjects were selected to simulate the 24-h flight mission, and the visual fatigue was alleviated by visual fatigue comprehensive protection measures after flight, and the visual function analyzer was used to detect the visual acuity before and after flight. Results: Compared with the pre-flight, the near-sightedness and the far-sightedness decreased after the flight. Conclusion: the comprehensive protective measures of visual fatigue can improve the comprehensive state of vision, alleviate the visual fatigue caused by 24 h simulated flight and improve the quality of visual function.
