2002年1月1日 · This three minute video describes and animates the events taking place in the eye during accommodation. Narration describes the events. Three dimensional animation shows convergence of the eyes. The view changes to a cut-away view of the eye interior to show pupillary constriction and changes in the shape of the lens.
Accommodation Reflex
The accommodation reflex of the eye is a reflex reaction when the eye looks at a distant object and then focuses on a near object. It is essential for a high degree of visual acuity. This 2D animation will guide you through the process of accommodation reflex, and help visualise how the eye changes in response to near vision.

Scientific Animation: EYE: accommodation or focusing …
Simulation of a light rays being focused by an emmetropic (normal) human eye during accommodation. Shows light rays diverging followed by the lens becoming more convex. Eyes may have refractive errors such as myopia and hypermetropia. With age, the lens degenerates and becomes increasingly opaque, a condition known as a cataract.
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 is an adjustment of the eye for near vision (Fig. 12.5). Three phenomena are involved: • Increased convexity of the lens. The suspensory ligament of the lens inserts peripherally into it. At rest, the ligament maintains tension on the periphery of the lens, such that it remains flat.
