Accommodation reflex - Wikipedia
The accommodation reflex (or accommodation-convergence reflex) is a reflex action of the eye, in response to focusing on a near object, then looking at a distant object (and vice versa), comprising coordinated changes in vergence, lens shape (accommodation) and pupil size.

2022年11月15日 · The accommodation reflex is the visual response for focusing on near objects. It also has the name of the accommodation-convergence reflex or the near reflex. It is synkinesis, which consists of the convergence of both eyes, contraction of the ciliary muscle resulting in a change in lens shape (accommodation), and pupillary constriction.
Accommodation Reflex - an overview | ScienceDirect Topics
The accommodation reflex (or near response) is a three-part reflex that brings near objects into focus through lens thickening, pupillary constriction, and inward rotation of the eyes—eye convergence. The ciliary bodies anchor suspensory ligaments, collectively called zonule, which stretch the lens and alter its refractive power.
调节反射 - 百度百科
调节反射（pupillary accomodation reflex）也称为瞳孔近反射（near reflex of the pupil），指的是眼视近物时引起的 反射 性双侧 瞳孔 缩小。 调节反射与检查：嘱患者注视正前方约30cm处检查者的食指，然后迅速移动食指至患者鼻根部，正常时可见双瞳缩小，称为调节反射。 视近物时产生瞳孔缩小可以减少折光系统的球面相差（像呈边缘模糊的现象）和色相差（像的边缘呈色彩模糊的现象），使得视网膜上的成像更加清晰。 [1] 调节反射（pupillary accomodation reflex）也称为 …

2023年3月8日 · Accommodation is the process in which the eyes see objects at different distances and maintain clear images of the objects by the convergence and divergence of light. Scheiner (1612) was the first to observe this phenomenon and he did this by making two tiny pinholes in a card, the distance between the pinholes were not wider than the diameter ...

2023年10月20日 · An accommodation reflex is a coordinated change which occurs when you switch focus from an object that’s far away to one that’s closer. It comprises of three separate processes: accommodation reaction, convergence and miosis, collectively known as the near triad. Let’s discuss each component of the near triad:
