Question
Chapter 17, Problem 11CP
Summary Introduction
To determine:
If the person is looking at the object that is far from them or is nearby, when their eye lens is more rounded.
Introduction:
The eye of the person contains a lens, which is made up of transparent proteinaceous tissue. This lens is very essential because, it is the reason that the light rays converge at the retina and forms an image. It lies behind the iris and changes its conformation according to the object’s position.

When the lens is more rounded, are you looking at an object that is close to you or far from you?
A female child, age 6, is brought to the health clinic for a routine checkup. To assess the child’s vision, the nurse should ask:
“Do you have any problems seeing different colors?”
“Do you have trouble seeing at night?”
“Do you have problems with glare?”
“How are you doing in school?”
Light rays from an object in the temporal half of the visual field strike which half of the retina?
