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 - 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.
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 …
Accommodation of Eye- Everything you need to know
2024年2月25日 · The difference between the dioptric power needed to focus at near point (P) and far point (R) is called amplitude of accommodation (A = P – R). In a specific distance amplitude of accommodation can be identify by using the formula:
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.

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 , …
Accommodation and Convergence - SpringerLink
2019年4月2日 · The accommodation is a reflex action of the eye, in response to focusing on a near target, then looking at a distance target (and vice versa), comprising coordinated changes in vergence, crystal lens shape and pupil size. Convergence is a vergence adduction movement...
When performing accommodation how should the pupil respond
Here is a simple table to summarize the pupil response: The accommodation reflex, also known as the near reflex, is a three-part response of the eye to focusing on objects at near distance. The three parts are: This reflex is coordinated by the Edinger-Westphal nucleus in the brainstem.

The accommodation reflex is crucial for clear vision across all distances. It underpins everyday tasks like reading, writing, and using digital devices. By enabling the eye to adjust its lens shape for optimal focus, this reflex ensures sharp vision for both near and distant objects.
The accommodation or near reflex - MedicosNotes.com
Accomodation reflex involve a triad of changes when a person looks at a nearby object. 1. Convergence of eye due to contraction of medial and lateral rectus muscle. 2. Miosis -constriction of pupils due to constrictor pupillae muscle contraction. 3.
