Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R).
Assertion (A): A myopic person cannot see distant objects clearly.
Reason (R): The image of distant objects forms behind the retina.
- ABoth (A) and (R) are true and (R) is the correct explanation of (A)
- BBoth (A) and (R) are true, but (R) is not the correct explanation of (A)
- C(A) is true, but (R) is false
- D(A) is false, but (R) is true
Show answer and explanation
Correct answer: (c) (A) is true, but (R) is false
Explanation
(A) is true and (R) is false.
In myopia (short-sightedness), the eyeball is too long or the eye lens is too strongly curved. Light from distant objects comes to a focus in front of the retina, not behind it, so distant objects look blurred while near objects are clear.
An image formed behind the retina is the case of hypermetropia (long-sightedness). Myopia is corrected with a concave (diverging) lens and hypermetropia with a convex lens.
