Question
Chapter 16, Problem 16DYKB
Summary Introduction
To determine:
The way in which the lens of eyes are able to focus images from a book that one is reading and then immediately focussing the image of children playing in the background.
Concept introduction:
Eyes help to see and view different objects by forming the image on the retina, which is a part of the eye that serves as a screen for the purpose of image formation. It is composed of certain parts like rods and cones, optic nerve, ciliary muscles or ciliary bodies. Another function of eyes is accommodation in dark and light areas.

Students have asked these similar questions
While viewing an object under low power you see a small organism at the edge of the field of vision. You move to the high-power lens, but the organism is no longer visible. What has occurred? How do you correct it?
Why are you unable to focus on images closer to your eye than the near point values you determined?
When the lens is more rounded, are you looking at an object that is close to you or far from you?
