	两个相同楔形棱镜反向等速旋转，使入射光束产生直线扫描。双眼视线经旋转双楔形棱镜直视六米处视标后并持续产生内聚与开散，训练一段时间被检者达到屈光度稳定及消除视觉疲劳。研究方法使用旋转双楔形棱镜及远方六米处视标，进行视觉训练，使眼外肌放松。视觉疲劳训练依近视屈光度的高低设定不同的训练时间。旋转双棱镜将提升眼球六条眼外肌之协调能力、眼内睫状肌的放松与调节作用及调节灵敏度，增加眼内外肌延展与收缩，造成破坏融像后让影像重整，如此能让影像维持在视网膜上六条眼外肌跟着运动。被检者的视力经过旋转双棱镜放松后，度数将趋于稳定，达到一般医生验光前习惯使用散瞳剂的方法。使用本创新方法，将使受测者在验光前免用散瞳剂让眼外肌放松，未来可做为验光师在验光流程前之参考步骤之一。<br />
Two same wedge prisms rotate in opposite direction to produce linear scanning of incident light beam. The binocular line of sight continuously converges and diverges after being viewed di-rectly at the ophthalmic eye chart of six meters by the two rotating wedge prisms after the pe-riod. The diopter of subjects was the stability and visual fatigue was eliminated. The research method uses the two rotating wedge prisms and six meters distant eye charts to carry on the eye exercise. The extraocular muscles of subjects were relaxed. Visual fatigue exercise sets the dif-ferent training time according to the diopter of myopia. The effect of eye exercise may strengthen the extraocular muscles of eyeball to move coordination of ability. The ciliary muscle was improved for relaxation, accommodation and adjustment sensitivity. The adduction and pursues of the object gaze can be increased. After subject’s vision passes through the eye exer-cise to reach the stability of visual acuity and the eye muscle to relax. Using this innovative method, the subjects will be free of atropine before optometry to relax the extraocular muscles. It can be used as one of the reference steps for optometrists before optometry in the future.
