Arguably, it may increase the depth of field by reducing the aperture of the eye, and thus reduce the amount of accommodation needed to bring the image in focus on the retina.There are many ways teachers can help kids who are struggling in school.Amanda Morin worked as a classroom teacher and as an early intervention specialist for 10 years.She is the author of The Everything Parent’s Guide to Special Education. Changes in contraction of the ciliary muscles alter the focal distance of the eye, causing nearer or future images to come into focus on the retina; this process is known as accommodation.The reflex, controlled by the parasympathetic nervous system, involves three responses: pupil constriction, lens accommodation, and convergence.It is dependent on cranial nerve II (afferent limb of reflex), superior centers (interneuron) and cranial nerve III (efferent limb of reflex).The change in the shape of the lens is controlled by the ciliary muscles inside the eye.

If you are trying to pick a movie to watch, and you really don't care, it's fine to say 'Whatever you want is ok with me'.

Accommodation usually acts like a reflex, including as part of the accommodation-vergence reflex, but it can also be consciously controlled.
