摘　　要：观看光栅3D显示的机理和人眼视觉生理存在矛盾,观看时间稍长将引起头痛、眼胀、复视等视疲劳症状,选择恰当的生理指标对视疲劳进行客观评价对其预防和消除具有重要意义。本研究探讨观看光栅3D显示对双眼视功能参数的影响。通过视觉检查筛选出24名被试者,并随机分成两组进行30分钟持续观看光栅3D显示2D视频和3D视频的实验。在观看实验前后分别对被试者进行视功能参数-双眼融合范围、AC/A值和CFF值的测量,并完成视疲劳和视觉诱导晕动症主观问卷。实验验证了融合范围、AC/A值和CFF值都随着视疲劳和VIMS的加剧而降低。2D组观看前后融合范围无差异,3D组观看前后融合范围有显著区别,而2D组和3D组的AC/A值和CFF值在观看前后都有显著差异。3D观看前后融合范围、AC/A值、CFF值降低幅度均比2D更大。实验结果表明,3D比2D造成了更严重的视疲劳和VIMS,而晕动症是导致观看光栅3D显示不舒适的主要原因。The mechanism of viewing autostereoscopic 3D display is contradictory to human visual physiology.Prolonged viewing time could cause headache,eye distension,double vision and other symptoms of visual fatigue.It is essential to choose the appropriate physiological indicators for objective evaluation so as to prevent and eliminate visual fatigue.The present research investigates the effect of viewing autostereoscopic 3D display on binocular visual function parameters.24 subjects are selected through visual examination.Subjects are randomly divided into two groups by whether watching 2D video or 3D video in 30 minutes.Objective evaluation indicators such as binocular fusion range,AC/A and CFF are measured before and after viewing.The subjects also complete subjective evaluation of visual fatigue and VIMS.The experiment verifies fusion range,AC/A and CFF decrease as the degree of visual fatigue and VIMS increases.With respect to fusion range,there is no obvious difference in 2D group when comparing after viewing to before,however,a statistically significant difference exists in 3D group.Both groups have significant differences in AC/A and CFF before and after viewing.Compared with the 2D group,3D group has a much more significantly decrease towards the three indicators during viewing times.The experimental results show that 3D material causes more severe visual fatigue and VIMS than 2D counterpart,while motion sickness is the main cause of discomfort in viewing autostereoscopic 3D display.
