Result
Your answer: —  Â·  Correct: D
Explanation

A person unable to read a newspaper without glasses is struggling with near vision, a hallmark of hypermetropia (farsightedness). In hypermetropia, the eyeball is often too short or the cornea too flat, causing light to focus behind the retina rather than on it. This makes close-up tasks like reading difficult, while distant objects may remain clear. While presbyopia also causes near-vision loss, it is specifically an age-related loss of lens flexibility typically occurring after age 40 [3]. Myopia, conversely, affects distance vision [2]. In standard medical and academic contexts, the general inability to see near objects clearly is defined as hypermetropia [3]. This condition is corrected using convex lenses to increase the eye's refractive power, bringing the focal point forward onto the retina [2].
