Question

A girl is long-sighted. Which statement is correct?
A. She sees close objects less clearly than a person with normal vision.
B. She sees distant objects more clearly than a person with normal vision.

Answer 1

Hint: Long-sightedness is a condition in which the picture of a close object forms behind the retina of the eyes. The light is concentrated behind the retina rather than on it in this case. As a result, adjacent objects are blurred.

Complete answer:

In long-sightedness or hypermetropia, the image of a nearby object lying at a distance of normal near the point $N$ at $25\,cm$ is formed behind the retina. This is due to her lens that is too flat or not curved enough, causing light from a close object (that will be diverging from a point) to be refracted excessively or short eyeball, leading it to converge behind the retina rather than on it.

This means the image isn't in focus. As a result, if a person has long-sightedness, surrounding objects will appear hazy.Because the light beams for a distant object are almost parallel, the light does not need to be as refracted, and she can easily focus the light onto her retina even with a less curved lens. As a result, she can clearly see faraway objects.

Hence option A is the correct answer.

Note: The least distance of distinct vision is the shortest distance at which objects may be viewed clearly without exertion. $25\,cm$ is the least distance of distinct vision for a young adult with normal vision. The image of an object is formed on the retina of the human eye.
