So, if the near point of an emmetrope is at 25 cm from the spectacle plane, the amplitude of accommodation is equal to − [−1/(25 ✕ 10)] = 4 D.The amplitude of accommodation declines from about 14 D at age 10 to about 0.5 D at age 60 (although the measured value is usually higher due to the depth of focus of the eye).Consequently, myopes require more accommodation and hyperopes less accommodation when they transfer from spectacles to contact lenses.
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.
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.
See convergence accommodation; proximal accommodation; reflex accommodation; resting state of accommodation.consensual accommodation Accommodation occurring in one eye when the other eye has received the dioptric stimulus.convergence accommodation 1.
Accommodation induced directly by a change in convergence. That component of accommodation induced by the binocular disparity of the retinal images. vergence accommodation.correction induced accommodation Ocular accommodation induced when changing from spectacles to contact lenses in near vision.
