双眼同时注视近距离目标时,要获得清晰的双眼单视,调节和辐辏必须同时发挥作用,正常情况下,二者总是互相协调。如果严重失调,就会有眼肌的不平衡或引起明显的不适。阐明调节和辐辏的关系在生理学、眼科屈光学和眼肌学方面都有重要的临床意义。调节性辐辏与调节之比率(即AC/A率)是调节和辐辏关系的一个重要方面。有关这方面的 When both eyes are looking at a close range target, to achieve clear binocular vision, both conditioning and convergence must work simultaneously and under normal circumstances the two are always in harmony. If you have a serious imbalance, there will be eye muscle imbalance or cause significant discomfort. To clarify the relationship between regulation and convergence in physiology, ophthalmology and ophthalmology have important clinical significance. The ratio of accommodative accommodative to accommodative (ie, AC / A ratio) is an important aspect of the relationship between accommodation and convergence. In this regard
