Match the List I with the List II from the combinations shown
(I) | Presbiopia | (A) | Sphero-cylindrical lens |
(II) | Hypermetropia | (B) | Convex lens of proper power may be used close to the eye |
(III) | Astigmatism | (C) | Concave lens of suitable focal length |
(IV) | Myopia | (D) | Bifocal lens of suitable focal length |
Text Solution
Verified by ExpertsThe correct answer is:
A
Step 1: Understand the conditions for each visual defect.
Presbyopia is the age-related loss of the eye's ability to focus on nearby objects, typically corrected with bifocal lenses (D).
Hypermetropia, or farsightedness, is corrected by using convex lenses (B), which allow the person to see close objects clearly.
Astigmatism occurs when the eye is not completely spherical, leading to blurred vision at all distances, and is corrected with sphero-cylindrical lenses (A).
Myopia, or nearsightedness, is corrected with concave lenses (C), which help focus distant objects on the retina.
Step 2: Match the conditions with the appropriate lenses.
Presbyopia matches with bifocal lenses (D); Hypermetropia matches with convex lenses (B); Astigmatism matches with sphero-cylindrical lenses (A); Myopia matches with concave lenses (C).
Thus, the correct matches are:
Presbyopia - D; Hypermetropia - B; Astigmatism - A; Myopia - C, confirming that the correct answer is:
Option A: I-A; II-C; III-B; IV-D.
