Explanation The ability of the eye to focus on nearby objects by the involvement of the ciliary muscles that are attached with the lens through the iris is a process called accommodation. The distant vision is the natural state. The diverging rays from nearby points must be bent more sharply to focus on the retina and to accomplish this, the lens is made round or bulges for the close vision...

Chapter 16, Problem 8CYU

Summary Introduction

To review:

The changes that occur in the shape of the lens when lens accommodates to see close objects.

Introduction:

The light rays coming from a distant point are parallel to one another as they reach the eye whereas, the light rays coming from a nearby point diverge as they enter the eye. The cornea of the eye regulates the entering of various light intensities and they reflect the light onto the lens to produce vision. The rod and the cone cells are the photoreceptors that are present in the retinal layer of the eye.
