Direction: In the Following Questions, A Statement of Assertion (A) I...
Assertion: Hypermetropia is the defect of the eye in which only farther objects are seen.
Reason: Hypermetropia is corrected by using converging lenses.
Explanation:
Hypermetropia, also known as farsightedness, is a common refractive error of the eye. In hypermetropia, the light entering the eye focuses behind the retina instead of directly on it. This results in difficulty in focusing on near objects, while distant objects may appear clearer.
Assertion (A) is true because hypermetropia is indeed a defect of the eye in which only farther objects are seen clearly. This is because the light rays from distant objects converge slightly before reaching the retina, allowing for clear vision.
Reason (R) is true because hypermetropia can be corrected using converging lenses. A converging lens is a convex lens that is thicker at the center and thinner at the edges. When a person with hypermetropia wears converging lenses, the lenses converge the incoming light rays before they enter the eye. This helps in properly focusing the light on the retina, allowing for clearer vision of both near and distant objects.
However, reason (R) is not the correct explanation of assertion (A) because the reason only explains how hypermetropia can be corrected, but it does not provide an explanation for why only farther objects are seen in hypermetropia. The assertion and reason are related, but the reason does not directly explain the assertion.
Therefore, the correct choice is option B where both the assertion (A) and reason (R) are true, but the reason (R) is not the correct explanation of the assertion (A).
