See minus lens method; push-up method.astigmatic accommodation Postulated unequal accommodation along different meridians of the eye attributed to a differential action of the ciliary muscle which would lead to a difference in the curvature of the surfaces of the crystalline lens along different meridians. meridional accommodation.closed-loop accommodation Accommodation response to visual stimuli in normal viewing conditions.

See open-loop accommodation.components of accommodation The process of accommodation is assumed to involve four components: reflex, vergence (convergence), proximal and tonic accommodation (also called resting state of accommodation).

Ophthalmology The automatic adjustment of the lens curvature, resulting in a change in the focal length of the eye, which brings images of objects from various distances into focus on the retina; the ability of the eye to focus at various distances, by changing lens shape.

Psychology In Piaget's theory of cognitive development, the change that occurs in an existing mental scheme or set of schemes due to assimilation of the experience of a new event or object. The adjustment of the eye for various distances whereby it is able to focus the image of an object on the retina by changing the curvature of the lens.

Spectacles induce less accommodation in myopes and more accommodation in hyperopes than that exerted by an emmetrope fixating at a given distance.

Contact lenses do not induce any different accommodation than that required for a given distance.

In some animals this adjustment occurs either as a result of an anteroposterior movement of the crystalline lens, or of an alteration in the curvature of the cornea.

See aniso-accommodation; ciliary muscle; accommodative reflex; Fincham's theory; Helmholtz's of accommodation theory.amplitude of accommodation The maximum amount of accommodation A that the eye can exert.

In emmetropia, the far point is at infinity; in myopia, it is at a finite distance in front of the eye; in hyperopia, it is a virtual point behind the eye (Fig. It could be due to uncorrected hyperopia or indicate accommodative insufficiency. See hyperopic of accommodation The amount by which the accommodative response of the eye is greater than the dioptric stimulus to accommodation, as occurs when fixating at distance, in a few individuals.

In the learning theory of Jean Piaget, the process through which a person's schema of understanding incorporates new experiences that do not fit existing ways of understanding the world.

See: adaptation The automatic process by which the eyes adjust their focus when the gaze is shifted from one point to another at a different distance.

In middle age PRESBYOPIA becomes apparent in all but the near-sighted. It is generally involuntary and made to see objects clearly at any distance.

In man (and primates), this adjustment is brought about by a change in the shape of the crystalline lens.

Changes during accommodation: (A), contraction of ciliary muscles; (B), approximation of ciliary muscles to lens; (C), relaxation of suspensory ligament; (D), increased curvature of anterior surface of lens.4 (in sociology) the reciprocal reconciliation of conflicts between individuals or groups concerning habits and customs, usually through a process of compromise, arbitration, or negotiation. Occupational medicine The changes made by a person or organisation to a workplace to allow a person with disabilities to work there.

  1. It is by far, the number one online attraction builder. For example: Instead of asking if she likes to travel, say, “If you could pack a suitcase and go anywhere in the world right now, where would you go and why! If it takes a woman more than a couple of days to respond, you will likely be deleted.
