Chapter 40.6, Problem 3CYL
Summary Introduction
To describe:
The differences between normal, nearsighted, and farsighted eyes and also explain the way through which defective focusing can be corrected by artificial lenses.
Introduction:
Eyes help to see and view different objects by forming the image on the retina, a part of eye serves as a screen for the purpose of image formation.

describe the differences between normal, nearsighted, andfarsighted eyes and explain how defective focusing can becorrected by artificial lenses?
Differentiate between near vision and distinct vision on the basis of shape of the eye lens.
Explain the normal functioning of the eye to allow us to have visual acuity.Â
What is meant by visual acuity? How does the eye adjust to facilitate this?
Specifically, how do changes in near-point accommodation and astigmatism affect acuity?
What is the problem with changes in near-point accommodation and astigmatism and why are they problematic? How can each of these be measured? Can these conditions be corrected? If so, how? Do these conditions change as we age?
