Explanation Accommodation is basically the process which elevates the len’srefractory power, the intrinsic muscles such as ciliary musclesconstrict which pulls the ciliary body anteriorly towards inward and to the pupil giving rise to the tension in the ciliary zonule. The nearest point on which the individual is able to focus clearly is known as the near point of vision and it displays the maximum bulge the lens is able to accomplish. In young adults having an emmetropic vision, the close point is 4 inches from the eye...

Chapter 13, Problem 11CYU

Summary Introduction

To review:

The reason behind the near point of vision moving farther away as the individual ages.

Introduction:

The light passes from the air into the eyes and it tavels sequentially via the cornea, lens, and finally moves through the entire neural layer of the retina in order for exciting the photoreceptor cells which are next to the pigmented layer.
