A disturbance of the physiological relation between accommodation and convergence which is defined by the AC/C ratio results in a manifest convergent squint. After a short reference to the typical accommodative esotropia, the atypical accommodative esotropia ("convergence excess") and its treatment with bifocal lenses are discussed in greater detail. Bifocal glasses are also used in the following disturbances of binocular vision: in partially accommodative convergent squint with a larger deviation in near fixation, in primary and postoperative microtropia with a larger deviation in near fixation, in esophoria with signs of decompensation in near fixation, with an intermittent exotropia of the divergence excess type. In the last-mentioned case they are use exclusively in preoperative diagnostics. The use of bifocals is simple and does not take much time; contrary to cyclospastic drugs, it has no undesirable side effects. Experience has shown that even after wearing bifocals for years there is no danger of a permanent accommodation insufficiency.
由调节性集合与集合性调节的生理关系紊乱（由AC/C比率定义）会导致明显的内斜视。在简要提及典型的调节性内斜视后，将更详细地讨论非典型调节性内斜视（“集合过度”）及其双焦点眼镜治疗方法。双焦点眼镜也用于以下双眼视觉障碍：近注视时偏差较大的部分调节性内斜视、近注视时偏差较大的原发性和术后微小斜视、近注视时出现失代偿体征的内隐斜、散开过度型间歇性外斜视。在最后一种情况下，双焦点眼镜仅用于术前诊断。使用双焦点眼镜简单且不耗时；与睫状肌痉挛药物相反，它没有不良副作用。经验表明，即使多年佩戴双焦点眼镜，也不存在永久性调节不足的风险。
