Consider the following statements : 1. In a person suffering from myopia, the image of a distant object is formed behind the retina. 2. Myopia can be corrected by using a concave lens. Which of the above statements is/are correct ?

Result
Your answer: —  Â·  Correct: B
Explanation

Myopia, also known as short-sightedness, is a refractive defect where a person can see nearby objects clearly but distant objects appear blurred. In a myopic eye, the image of a distant object is formed in front of the retina rather than on it [c1][t3]. This occurs because the eyeball is too long or the eye lens has excessive curvature, leading to high converging power [t3][t4]. Consequently, statement 1 is incorrect as it claims the image forms behind the retina (a characteristic of hypermetropia) [t3][t8]. To correct myopia, a concave (diverging) lens of suitable power is used [c1][t1]. The concave lens diverges the incoming parallel light rays before they enter the eye, allowing them to eventually converge exactly on the retina, thereby restoring clear distant vision [t3][t7]. Thus, statement 2 is correct.
