    en.wikipedia.org/wiki/Accommodation_reflex

    Light from a single point of a distant object and light from a single point of a near object being brought to a focus. 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.

  3. Vestibulo-ocular reflex - Wikipedia

    en.wikipedia.org/wiki/Vestibulo-ocular_reflex

    The vestibulo-ocular reflex (VOR) is a reflex that acts to stabilize gaze during head movement, with eye movement due to activation of the vestibular system, it is also known as the cervico-ocular reflex. The reflex acts to stabilize images on the retinas of the eye during head movement. Gaze is held steadily on a location by producing eye ...

    en.wikipedia.org/wiki/List_of_reflexes

    A list of reflexes in humans. Abdominal reflex; Accommodation reflex — coordinated changes in the vergence, lens shape and pupil size when looking at a distant object after a near object. Acoustic reflex or attenuation reflex — contraction of the stapedius and tensor tympani muscles in the middle ear in response to high sound intensities.

    en.wikipedia.org/wiki/Optokinetic_response

    The optokinetic reflex (OKR), also referred to as the optokinetic response, or optokinetic nystagmus (OKN), is a compensatory reflex that supports visual image stabilization. [1] The purpose of OKR is to prevent motion blur on the retina that would otherwise occur when an animal moves its head or navigates through its environment.

  6. Vestibular system - Wikipedia

    To nuclei of cranial nerves III, IV, and VI. Signals sent to these nerves cause the vestibular-ocular reflex. They allow the eyes to fix on a moving object while staying in focus. To the reticular formation. Signals sent to the reticular formation signal the new posture the body has taken on, and how to adjust circulation and breathing due to ...

    Vestibulo-ocular reflexReflex where rotation of the head causes eye movement to stabilize vision; Oculomotor nerve – Cranial nerve III, for eye movements; Oculomotor nucleus – Cluster of neurons in the midbrain; Edinger–Westphal nucleus – One of two nuclei of the oculomotor nerve

  8. Human eye - Wikipedia

    en.wikipedia.org/wiki/Human_eye

    The vestibulo-ocular reflex is a reflex eye movement that stabilizes images on the retina during head movement by producing an eye movement in the direction opposite to head movement in response to neural input from the vestibular system of the inner ear, thus maintaining the image in the centre of the visual field. For example, when the head ...
