When looking at a far object with two eyes, relaxation of convergence and accommodation occurred and accompanied by binocular fusion. Using this phenomenon a method of binocular fusion of targets was designed, that is the distance between two targets are just the same as the distance between two visual lines, while looking at a far object. During the images of the targets are fused, the accommodation and convergence are relaxed concomitantly; thus a result of correction of pseudomyopia and prevention of myopia is achieved. By means of binocular fusion, the eye muscle exercises were conducted and resulted in not only the far point further but also the near point closer. The skiascopic examination carried out at the same time of binocular fusion showed that the degrees of relaxed accommodation was 97.9% that of looking at an object in far distance. The above results indicated that the binocular fusion method had excellent effect on the prevention of myopia. This method is simple and feasible, conforms to the visual physiology, and thus can be widely adopted.
当用双眼注视远处物体时，集合和调节放松，并伴有双眼融合。利用这一现象设计了一种目标双眼融合的方法，即注视远处物体时，两个目标之间的距离与两条视线之间的距离相同。在目标图像融合过程中，调节和集合同时放松；从而实现了假性近视的矫正和近视的预防。通过双眼融合进行眼肌锻炼，不仅远点变远，近点也变近。在双眼融合的同时进行检影检查发现，调节放松的程度为注视远处物体时的97.9%。上述结果表明，双眼融合方法对预防近视有良好效果。该方法简单可行，符合视觉生理，因此可广泛采用。
