Abstract：Objective To provide reference data for further standardizing the current scotopic vision training pro-gram by analyzing the results of scotopic vision experience training of aircrews and studying the related factors that affect the training results.Methods This study introduced the current trial scotopic vision physiological experience training pro-gram based on T2/YSX-1 scotopic vision physiological phenomenon experience system,and analyzed the related factors affecting the training results.Results Photopic vision in the night vision goggles(NVGs)calibration and paracentral training in the probability distribution was statistically significant(P＜0.05);there was significant difference in depth perception test between different aircraft types(P＜0.05);saccade and gaze had statistical significance in overcoming scotopic myopia(P＜0.05);in the trial standard,there was no significant difference between head-up with naked eyes and head-up with NVGs in depth perception test(P＞0.05);there were statistically significant differences in the results of over-head test with NVGs between head-up test with naked eyes and head-up test with NVGs(all P＜0.001).Conclusion Photopic vision is an important factor affecting the results of NVGs focusing and paracentral training;sac-cade can effectively shorten the myopic distance and find the target earlier;the type of aircraft and the visual angle are the related factors affecting the distance judgment and stereo vision.
