The ciliary muscle is controlled by the parasympathetic system, which is triggered by an out of focus retinal image. See push-up method; near point rule; near point sphere; Scheiner's test.negative accommodation 1.
See convergence accommodation; proximal accommodation; accommodative response; ciliary muscle; near reflex.meridional accommodation See astigmatic accommodation.microfluctuations of accommodation Involuntary variations in the contraction of the intraocular muscles responsible for accommodation and resulting in changes of about 0.1-0.5 D with a frequency of 0.5-2.5 point of accommodation The nearest point in space that is conjugate with the foveola when exerting the maximum accommodative effort. A relaxation of accommodation below the apparent zero level or when shifting from near to distance vision. See relative amplitude of accommodation.objective accommodation Accommodation measured without the subject's judgment.
It is expressed in dioptres, as the difference between the far point and the near point measured with respect either to the spectacle plane or the corneal apex or some other reference point.
Thus,where B is the near point vergence and K is the far point vergence. In the emmetropic eye, A = −B, because the far point is at infinity and K = 0.
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.
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.
Fringe ophthalmology Near and far focusing—an exercise in Bates vision training, which consists of changing the point of focus from near to far distances multiple times.
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.
