虚拟现实（VR）头显通过在非常靠近眼睛的屏幕上显示图像来创造沉浸感，这些图像通过高倍镜头观看。在这里，我们调查这种观看安排是否改变双眼的状态，以及它是否可能提供近视发展的刺激。我们比较了在室内和室外环境中，在真实的和虚拟世界中40分钟的试验后的双眼状态。我们还测量了眼脉络膜厚度的变化，以评估可能存在的眼生长和近视发展的信号。我们发现，暴露于4种环境中的每一种后，双眼远近位姿势、注视稳定性、调节幅度和立体视觉的变化没有差异。因此，我们没有发现VR光学装置在短期内对眼睛的双眼状态有不利影响的证据。脉络膜厚度在任何一个真实的世界试验后都没有改变，但是在每个VR试验后都有显著的增厚（<10微米）（p < 0.001）。我们观察到的脉络膜增厚表明，VR耳机可能不是近视源性刺激，尽管涉及非常近的观看距离。
Virtual Reality (VR) headsets create immersion by displaying images on screens placed very close to the eyes, which are viewed through high powered lenses. Here we investigate whether this viewing arrangement alters the binocular status of the eyes, and whether it is likely to provide a stimulus for myopia development. We compared binocular status after 40-minute trials in indoor and outdoor environments, in both real and virtual worlds. We also measured the change in thickness of the ocular choroid, to assess the likely presence of signals for ocular growth and myopia development. We found that changes in binocular posture at distance and near, gaze stability, amplitude of accommodation and stereopsis were not different after exposure to each of the 4 environments. Thus, we found no evidence that the VR optical arrangement had an adverse effect on the binocular status of the eyes in the short term. Choroidal thickness did not change after either real world trial, but there was a significant thickening (≈10 microns) after each VR trial (p < 0.001). The choroidal thickening which we observed suggest that a VR headset may not be a myopiagenic stimulus, despite the very close viewing distances involved.
