Explanation

Hyperopia, or farsightedness, is a refractive error where near objects appear blurry.
This occurs because the eyeball is anatomically short or the lens system has insufficient refractive power, causing light from near objects to be focused at a point theoretically behind the retina.
The primary symptom is an inability to focus on close-up tasks, such as reading, which directly matches the scenario in the question.
While young individuals may compensate for mild hyperopia through accommodation (the eye's focusing mechanism), this effort can lead to eyestrain and headaches.

Option A: Myopia, or nearsightedness, is characterized by the ability to see near objects clearly, while distant objects appear blurred. This is the opposite of the symptom described.
Option B: Astigmatism is caused by an irregular shape of the cornea or lens, which results in distorted or blurry vision at all distances, not just near.
Option C: Presbyopia presents with the same symptom (difficulty with near vision) but is specifically the age-related loss of the eye's ability to focus. Hyperopia is the underlying refractive error itself. Without the patient's age, hyperopia is the more general and fundamental diagnosis for the described refractive state.

Clinical Relevance

Nursing practice connection: Use the key finding related to Refractive errors of the eye and their characteristic symptoms to guide bedside assessment, documentation, and the next nursing action.
Recognizing the signs of refractive errors is a key nursing assessment skill, especially in pediatric and school health settings, as uncorrected vision problems can impact learning and development.
Patient education is crucial. A nurse should be able to explain the difference between these conditions in simple terms and emphasize the importance of regular eye exams and wearing corrective lenses as prescribed to prevent eyestrain, headaches, and potential complications like amblyopia in children.
What if? If the patient was 45 years old and reported that their arms 'feel too short' when trying to read, the most likely diagnosis would shift to presbyopia, as this is the classic age of onset and description for age-related focusing decline.

How to Approach the Question

First, identify the key symptom presented in the question stem: 'unable to read words placed at a normal distance.' This clearly points to a problem with near vision.
Next, systematically evaluate each option based on its definition.
Recall that Myopia (nearsightedness) affects distant vision.
Recall that Astigmatism affects vision at all distances.
This leaves Hyperopia and Presbyopia, both of which affect near vision. Differentiate between them: Hyperopia is a refractive error based on eye shape, while Presbyopia is an age-related loss of focusing ability.
Since no age is given, select Hyperopia as the more fundamental and general term for the refractive error causing the symptom.
