对光聚散和会聚调节的测量结果表明，会聚调节是一种非条件反射。会聚诱导的调节等于直到24岁的会聚，并且在该年龄以上，它逐渐减小。调节仅由视觉轴的光聚散和会聚控制，调节以反射的方式对其作出反应。这些因素可以在正常的双眼视觉中一致地起作用，或者在确定相对幅度的情况下相反地起作用。该理论是先进的，在单眼固定过程中发生的反射性收敛不是次要的调节，但所需的收敛努力的表现形式，以诱导必要的调节，以增加来自光聚散刺激。
Measurements of accommoda-tion to light vergence and convergence in human subjects indicate that accommodation is induced by convergence as an unconditioned reflex. Convergence -induced accommodation is equal to the convergence up to the age of 24 years, and above that age, it gradually diminishes. Accommodation is controlled only by light vergence and convergence of the visual axes, to which it reacts in a reflex manner. These factors may act in unison as in normal binocular vision, or in opposition as in the case when relative amplitudes are determined. The theory is advanced that accommodative convergence occurring during monocular fixation is not secondary to accommodation, but a manifestation of the convergence effort required to induce the necessary accommodation to augment that which derives from the light vergence stimulus.
