In human vision, one eye is usually stronger than the other. This is called ocular dominance. Extremely imbalanced ocular dominance can be found among certain patient groups, for example, in patients with amblyopia. Here, we introduce a novel method to rebalance ocular dominance. We developed an altered-reality system that subjects used to interact with the natural world, the appearance of which was changed through a real-time image process. Several daily adaptation sessions lasting 3 hr each reduced sensory ocular dominance in adults who were not diagnosed with amblyopia and improved vision in patients with amblyopia. Surprising additional strengthening was found over the subsequent 2 months, when subjects experienced natural vision only. Our method effectively trains subjects to use both eyes in the wide variety of everyday tasks. The transfer of this training to everyday vision likely produced the continuing growth in effects during the months after the training. These findings are promising for the application of this method in future clinical research on amblyopia.
在人类视觉中，通常一只眼睛比另一只眼睛更强。这被称为眼优势。在某些患者群体中，如弱视患者中，可以发现非常不平衡的眼优势。在这里，我们介绍一种重新平衡眼优势的新方法。我们开发了一种改变现实的系统，让患者使用该系统与自然世界进行交互，通过实时图像处理来改变自然世界的外观。几个持续 3 小时的日常适应训练，降低了未被诊断为弱视的成年人的感觉眼优势，并改善了弱视患者的视力。令人惊讶的是，在随后的 2 个月内，当受试者只体验自然视觉时，还发现了额外的增强。我们的方法有效地训练受试者在日常生活的各种任务中同时使用两只眼睛。这种训练对日常视觉的转移可能导致了训练结束后几个月内效果的持续增长。这些发现为该方法在未来弱视临床研究中的应用提供了希望。
