在麦克斯韦尔显示的增强现实中注视时的眼调节和瞳孔反应。

PURPOSE: This study aimed to investigate the changes in ocular refraction and pupillary diameter during fixation on augmented reality (AR) images using a Maxwellian display. METHODS: Twenty-two healthy young volunteers (average age, 20.7 ± 0.5 years) wore a Maxwellian display device in front of their right eye and fixated on an asterisk displayed on both a liquid-crystal display (real target) and a Maxwellian display (AR target) for 29 seconds (real as a baseline for 3 seconds, AR for 13 seconds, and real for 13 seconds) at distances of 5.0, 0.5, 0.33, and 0.2 meters. A binocular open-view autorefractometer was used to measure the ocular refraction and pupillary diameter of the left eye. RESULTS: Accommodative (5.0 meters, 0.28 ± 0.29 diopter [D]; 0.5 meter, -0.12 ± 0.35 D; 0.33 meter, -0.43 ± 0.57 D; 0.2 meter, -1.20 ± 0.82 D) and pupillary (5.0 meters, 0.07 ± 0.22 mm; 0.5 meter, -0.08 ± 0.17 mm; 0.33 meter, -0.16 ± 0.20 mm; 0.2 meter, -0.25 ± 0.24 mm) responses were negative when the real target distances were farther away. The accommodative response was significantly and positively correlated with the pupillary response during fixation on the AR target (R2 = 0.187, P < 0.001). CONCLUSIONS: Fixating on AR images using a Maxwellian display induces accommodative and pupillary responses. Accommodative responses depend on the distance between real objects. Overall, the Maxwellian display does not completely eliminate accommodation in real space.

目的：本研究旨在探讨使用麦克斯韦镜在增强现实（AR）图像上固定时眼屈光和瞳孔直径的变化。

方法：22 名健康年轻志愿者（平均年龄 20.7±0.5 岁）在右眼前佩戴麦克斯韦镜设备，并注视液晶显示器（真实目标）和麦克斯韦镜（AR 目标）上显示的一个星号 29 秒（真实目标 3 秒，AR 目标 13 秒，真实目标 13 秒），距离分别为 5.0、0.5、0.33 和 0.2 米。双眼开放式自动折射计用于测量左眼的眼屈光和瞳孔直径。

结果：调节（5.0 米，0.28±0.29 屈光度[D]；0.5 米，-0.12±0.35 D；0.33 米，-0.43±0.57 D；0.2 米，-1.20±0.82 D）和瞳孔（5.0 米，0.07±0.22 毫米；0.5 米，-0.08±0.17 毫米；0.33 米，-0.16±0.20 毫米；0.2 米，-0.25±0.24 毫米）反应在真实目标距离较远时为负。在注视 AR 目标时，调节反应与瞳孔反应显著正相关（R2=0.187，P<0.001）。

结论：使用麦克斯韦镜在 AR 图像上固定会引起调节和瞳孔反应。调节反应取决于真实物体之间的距离。总的来说，麦克斯韦镜并不能完全消除真实空间中的调节。
