项目摘要

We have evaluated the effect on the human visual system of viewing 2D or 3D movies. Additionally, we investigated the gain of torsional optokinetic nystagmus (tOKN) and pupillary movements during near reflex.The pupil diameter and the horizontal eye position of bilateral eyes during near response were measured by using the prototype of a "Near Triad Meter" (Hamamatsu Photonics, Japan) before and after viewing 2D (90 min)or 3D (30 or 15 min) movies. We analyzed.the distortion ratio of pupillary movement (PDR, calculated as mydriasis duration/miosis duration), pupil constriction ratio (PCR, calculated as (maximum diameter-minimum diameter)/maximum diameter), and the amount of convergence (CONY). A significant decrease in PDR was observed immediately following 30 minutes' 3D viewing. Significant changes were not observed in the grand averages of PCR, CONY, and the parameters of accommodative step responses. No effects were observed after viewing 2D movies.Three-dimensional eye movements were measured by using dual-search coil methods. A rotating random dot pattern (22゜ in diameter, +/- 54゜/s) was projected on the virtual screen of the optical see-through head-mounted display (HMD). The horizontal disparity was induced by changing the distance between the fixated target (a red LED) and the subject systematically (1-3 m) or by the prism (+1.5--0.5 prism-diopter). The average gain with zero horizontal disparity was significantly higher than the gain with crossed disparity and uncrossed disparity.The horizontal disparity of optokinetic stimulus affects tOKN but accommodation does not. Non-zero horizontal disparity decreases the gain of tOKN. Three-dimensional viewing of virtual images modified the waveform of pupillary movements during near response without affecting vergence. The effect of 3-D viewing could be quantified by PDR These parameters are good candidates for the formulation of a common standard to evaluate the effects on visual system.

我们已经评估了观看2D或3D电影对人类视觉系统的影响。在观看2D(90min)或3D(30min或15min)电影前和观看3D(30min或15min)电影之前和之后，使用日本滨松光电公司的近三联仪原型测量了双眼在近反射时的瞳孔直径和水平眼位。分析瞳孔运动变形率(PDR，计算为散瞳持续时间/散瞳持续时间)、瞳孔收缩比(Pcr，计算为(最大直径-最小直径)/最大直径)和聚集量(Cony)。在3D观看30分钟后，立即观察到PDR显著下降。在PCR值、CONY值和调节性阶跃反应参数中没有观察到明显的变化。在观看2D电影后，没有观察到任何效果。使用双搜索线圈方法测量三维眼动。在光学透明头戴式显示器的虚拟屏幕上投射了一个旋转的随机点图案(直径22゜，+/-54゜/S)。水平视差是通过系统地改变注视目标(红色LED)与被摄体之间的距离(1~3m)或通过棱镜(+1.5~-0.5棱镜屈光度)来产生的。水平视差为零的平均增益显著高于交叉视差和非交叉视差的平均增益，视动刺激的水平视差影响TOKN，而调节不影响。非零的水平视差降低了tOKN的增益。虚拟图像的三维观看改变了近反应期间的瞳孔运动波形，而不影响收敛。三维视觉效果可以用PDR来量化，这些参数是制定评估视觉系统影响的共同标准的很好的候选者。
