视觉功能的最重要表现就是视力,没有器质性病变而矫正视力又达不到正常的眼,就是弱视眼,是由于各种原因使视力没有得到发育和锻炼所造成的。其治疗多以刺激视觉细胞或调正两眼物像等方法为主。近年来,将光学领域内研究发展起来的空间频率特性的概念引进视觉系统。生理学和神经解剖学方面的研究表明,视皮质中的细胞对不同空间 The most important manifestation of visual function is visual acuity, without organic disease and visual acuity can not reach the normal eye, is the amblyopic eye, is due to various reasons that vision has not been developed and exercised caused. The treatment of many to stimulate the visual cells or correct the two objects and other methods based. In recent years, the concept of spatial frequency characteristics developed in the field of optics has been introduced into the visual system. Studies in physiology and neuroanatomy have shown that cells in the visual cortex respond to different spaces
