本研究利用新型速度可調的旋轉稜鏡視力訓練機結合動態視標以建立學童近視度數控制方法。使用眼鏡式旋轉稜鏡訓練機，配合目視前方六米動態視標，進行視力訓練。在近視度數1.50D時訓練週期為七分鐘，或依近視度數高低設定不同訓練時間。稜鏡旋轉目的是使六條眼肌肉外拉及眼球追隨運動，造成破壞融像及讓影像重整，達到學童視力具融合為單一影像的視覺能力。利用稜鏡旋轉造成視覺的運動性融像，讓視網膜上的影像產生不對稱，但為了能維持影像在視網膜對應點上，六條眼肌肉跟著運動。
經過三個月實驗，學童經過旋轉稜鏡視力訓練後，眼肌肉放鬆及視力變明亮，近視屈光度平均減少0.50D，最高減少可達0.75D。持續每週訓練1次，視力會更穩定。實驗顯示本研究可有效控制學童近數視度數。
In this study, the use of new rotary prism vision training machine combined with dynamic visual standard to establish the school myopia control method, rotating prism speed can be changed. This study uses glasses-type rotating prism training machine, with the visual front six meters dynamic visual standard, for visual training. Myopia 1.50D for seven minutes for the training cycle, or according to the degree of myopia set the training time. Prism rotation is to make six eyes outside the muscle pull and follow the movement of the eye to create damage to the image and make the image reorganization, to achieve the integration of school vision for a single image of the visual ability. The use of prism rotation caused by visual movement of the image of the retina to produce asymmetry of the image, but in order to maintain the image in the retina corresponding point, so that six eye muscles must be forced to exercise.
Students after the rotation of the prism after visual training, eye muscle relaxation and vision become bright, myopia diopter decreased by an average of 0.50D, the maximum reduction of 0.75D (data after three months of experiment). Continuing training once a week, vision is more stable, the experiment shows enough to provide school children control degree. This study can be used as a method to effectively control the number of visually different children.
