Binocular rivalry (BR) is a visual perception phenomenon that occurs when each eye perceives different images and stimuli, causing alternating monocular dominance. To measure BR, many studies have used two monocular conflicting images to induce monocular alternations. Here we chose a group of participants with oblique astigmatism (OA) and who produced blur on the orthogonal oblique meridian in each eye, resulting in two conflicting images, which may enhance the stimulation of monocular alternations. Our results show that OA participants tend to have a high rate of BR when viewing natural images, whereas the control group does not have BR for the same images. We suggest that this low ability to fuse could indicate the presence of a trace due to uncorrected vision during the critical period, which could be retained in the adult brain.
双眼竞争（BR）是一种视觉感知现象，当每只眼睛感知到不同的图像和刺激时会发生，导致交替的单眼优势。为了测量 BR，许多研究使用两个单眼冲突的图像来诱导单眼交替。在这里，我们选择了一组患有斜散光（OA）的参与者，他们在每只眼睛的正交斜子午线上产生模糊，从而产生两个冲突的图像，这可能会增强单眼交替的刺激。我们的结果表明，OA 参与者在观看自然图像时往往具有较高的 BR 率，而对照组则不会对相同的图像产生 BR。我们认为，这种低融合能力可能表明在关键期存在未矫正视力的痕迹，这些痕迹可能会保留在成年人大脑中。
