We developed an amblyopia-training device, which can be used easily and inexpensively under binocular conditions with polarizing films. The device uses two polarizing films: one is attached to the training target (such as monitors and books), while the other is attached to the lens of glasses that cover the healthy eye with the absorption axis rotated 90 degrees. This allows the target to be presented only to the amblyopic eye under binocular conditions. Amblyopia training with this device was performed for 1 h per day in 14 patients with anisometropic amblyopia. The training resulted in a significant improvement in visual acuity, and a significant correlation was observed between the improvement in visual acuity and the adherence rate, indicating the effectiveness of the device for amblyopia training under binocular conditions.

我们开发了一种弱视训练装置，它可以在带有偏光膜的双眼条件下轻松且廉价地使用。该设备使用两片偏光膜：一层贴在训练目标（如显示器和书籍）上，另一片贴在覆盖健康眼睛的眼镜镜片上，吸收轴旋转90度。这允许在双眼条件下仅将目标呈现给弱视眼。14 名屈光参差性弱视患者每天使用该设备进行 1 小时的弱视训练。训练导致视力显着提高，并且观察到视力提高与依从率之间存在显着相关性，表明该设备在双眼条件下进行弱视训练的有效性。
