Objective To explore the effects of 12-h flight on the visual system and lay a theoretical foundation for developing visual fatigue protection measures. Methods The visual function of six healthy subjects tested with Optec-6500 (Stereo Corp, USA) for 12-h flight. Different spatial frequencies (1, 3, 6, 12, 18 cpd) and distant vision and near vision were compared with preflight and postflight. Results Compared with preflight, the contrast sensitivity CS value (frequency 3) was significantly lower than postflight. The contrast sensitivity CS value (frequency 1.5, 6, 12, 18) has a downward trend during flight. Conclusion 12 h of flight and sleep deprivation may affect visual contrast and central visual function quality. It is vital to formulate systematic, scientific and rapid visual fatigue protection measures to reduce long-term flight and sleep deprivation to reduce the visual information load of flight personnel.
