| | Accommodation of the Eye to Different Focus Distance |
 | | To model the accommodation of the eye, the scale model eye was used with the cornea through the front surface of the lens held constant at the model values. | | | Accommodation of the Eye to Different Focus Distance | | | The increased accommodation is due largely to highly developed sphincter muscles which vary the curvature of the front of the lens. |

| | The gradual loss of the eye's ability to change focus (accommodation) for seeing near objects caused by the lens becoming less elastic; associated with aging; occurs in almost all people over age 45. | | | A condition in which one eye involuntarily turns inward toward the other when the eyes are not focused on an object. | | | The ability of the eye to change its focus from distant to near objects; process achieved by the lens changing its shape. |

| | The accommodation reflex is caused by the contraction of the ciliary muscles of the eye that attach to the lens via the suspensory ligaments. | | | The accommodation reflex changes the shape of the lens to allow near vision. | | | The ability of the human eye to form a sharp image is determined by the shape of the eyeball and lens, and how structures in the eye such as the iris and lens reflexively respond to light stimuli. |

| | Eye - Wikipedia, the free encyclopedia |
| | While there are many changes of significance in the nondiseased eye, the most functionally important changes seem to be a reduction in pupil size and the loss of accommodation or focusing capability (presbyopia). | | | Many complex organisms, including some mammals, birds, reptiles and fish, have two eyes which may be placed on the same plane to be interpreted as a single three-dimensional "image" (binocular vision), as in humans; or on different planes producing two separate "images" (monocular vision), such as in rabbits and chameleons. | | | Blinking the eyes is, of course, also a reflex. |

| | Blinking the eyes is, of course, also a reflex. | | | In humans, the eyebrows redirect flowing substances (usually rainwater) away from the eye. | | | At this point, the optokinetic reflex kicks in, and moves the eye back to the point where it first saw the tree (through a saccade). |

| | Pupillary constriction (from the pupillary constrictor muscle) and convergence of the eye muscles (via the medial rectus muscles) also contribute to the accommodation reflex. | | | The action of the ciliary nerves on the constrictor pupillea causes this muscle to constrict and reduces the size of the lense in response to the intensity of the light entering the eye. | | | This is the reflex that allows us to view things close to our eyes, with both eyes. |

| | However, atropine does have side effects that should be considered: light sensitivity (because the eye is constantly dilated); flushing or slower heart rate in some children, especially if multiple drops are used; and possible paralysis of the ciliary muscle after long-term atropine use, which could affect the eye's accommodation, or ability to change focus. | | | Amblyopia, also known as lazy eye, is a vision problem that affects just two to three percent of the population, but if left uncorrected, it can have a very big impact on their lives. | | | Amblyopic children can be treated with vision therapy (which often includes patching one eye), atropine eye drops, the correct prescription for nearsightedness or farsightedness, or surgery. |

| | Accommodation is the ability of the eye to change focus to clearly see objects at different distances. | | | Amplitude of accommodation is the difference, expressed in diopters, between the far point of accommodation and the near point of accommodation measured clinically from the spectacle plane. | | | Accommodative vergence is the component of convergence which occurs as a direct result of accommodation. |

| | Associated with this accommodation reflex is constriction of the pupil, which results in increasing the depth of field of focus at the closer focusing distance. | | | The process of accommodation involves reflex adjustment of lens diameter and reflexes of convergence and divergence, as well as reflex adjustment of pupillary diameter. | | | With the lens accommodated for distant vision (more than 20 feet away, so that the light rays are approaching parallel to each other), the total refractive power of the eye (cornea plus lens) is about 59 diopters. |

| | The consensual light reflex is the simultaneous contraction of the other eye, and is usually less than the direct reflex. | | | As it does so, the pupil constricts reflexively this is the accommodation reflex. | | | This reflex can be elicited by asking the patient to look at a distant object and then focus on a finger held several inches away from their face. |

| | See Clearly Method: Do Eye Exercises Improve Vision? - AllAboutVision.com |
| | Certain eye exercises are designed to relieve so-called spasm of accommodation, believed to be an environmentally induced disruption of the eye's focusing capacity. | | | A long-standing criticism of eye exercises, coming from both mainstream optometrists as well as from eye surgeons, is the absence of reliable evidence that they can reduce your reliance on corrective lenses at all, let alone eliminate it. | | | It's important to note that while many people think of such eye exercises as vision therapy, most vision therapists do not wish to be associated with self-directed programs. |

| | Because the accommodation reflex pathway is distinct from the pupillary light reflex pathway the accommodation reflex is unaffected. | | | This results in a loss of both the direct and consensual pupillary light reflex when light is shined in the eye on the affected side. | | | As a result of this damage, signals carried by CN II from the retina are not relayed via the pretectal nucleus on the affected side to the Edinger-Westphal nuclei. |

| | If the eye is focusing on a distant object the muscles relax, causing the ligaments to tighten and the lens to lengthen. | | | This means that the nerve fibres actually pass over the sensitive part of the eye, but, odd as it may seem, no disturbance in vision is caused. | | | Held in place by ligaments, which connect to the ciliary body, the lens can also change shape to focus on objects at different distances – a reflex known as accommodation. |
