What is accommodation in the human eye?
Accommodation of the eye refers to the act of physiologically adjusting crystalline lens elements to alter the refractive power and bring objects that are closer to the eye into sharp focus.
What is physiological accommodation?
Excerpt. The accommodation reflex is the visual response for focusing on near objects. It is synkinesis which consists of the convergence of both eyes, contraction of the ciliary muscle resulting in a change of lens shape (accommodation), and pupillary constriction.
What do you mean by the term accommodation?
Accommodation is all about making room — it can mean a room or place where you will stay or an agreement about sharing something. When you are accommodating someone, you are making room for them or special circumstances for them.
What is accommodation in biology?
In biology, it refers to an adjustment or adaptation. For example, in ophthalmology, accommodation pertains to the adjustment of the eye for various distances resulting in pupil constriction or dilatation. In this regard, the eye adjusts to a change of the distance.
What is accommodation in sociology?
According to Gillin and Gillin (1948), ‘accommodation is the term used by sociologists to describe a process by which competing and conflicting individuals and groups adjust their relationships to each other in order to overcome the difficulties which arise in competition, contravention or conflict’.
What is the mechanism of accommodation?
According to the classical view, as described by Helmholtz,9 accommodation occurs by contraction (forward and inward movement) of the ciliary muscle and relaxation of the zonules that attach the ciliary body to the lens; as a result, the lens thickens and becomes more steeply curved, increasing the refractive power of …
What is the importance of accommodation?

What is the meaning of accommodation in basic science?
a : the automatic adjustment of the eye for seeing at different distances effected chiefly by changes in the convexity of the crystalline lens. b : the range over which such adjustment is possible.
What is the process of accommodation?
Accommodation is the process of adjusting the lens of the eye so that you can see both near and far objects clearly. This process is very rapid although changing accommodation from a near object to a far object is faster than going from a far object to a near object (Kirchhof, 1950).

What is accommodation in eyesight?
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 of the pupil; an object was viewed through the pinhole.
What is accommodation in vision?
Accommodation refers to your eyes’ ability to see things that are both close up and far away. If your pupils are nonreactive to accommodation, it means they don’t adjust when you try to shift your focus to an object in the distance or near your face. You can also think of PERRLA as a sentence.
