Match the column.
Column –I | Column –II |
(i) Myopia | [A] Bifocal lens |
(ii) Hypermetropia | [B] Cylindrical lens |
(iii) Presbyopia | [C] Concave lens |
(iv) Astigmatism | [D] Convex lens |
Correct Matrix Matching
Text Solution
Verified by ExpertsThe correct answer is:
C
Step 1: Understand the types of vision problems and the corresponding lenses used to correct them.
Myopia (nearsightedness) is corrected using a concave lens, which allows light to diverge before it reaches the eye, thus focusing images further away correctly on the retina.
Hypermetropia (farsightedness) is corrected with a convex lens, which converges light rays to focus on the retina, allowing nearby objects to be seen clearly.
Presbyopia is an age-related condition causing difficulty in seeing close objects, typically corrected with bifocal lenses that combine two different optical powers in one lens.
Astigmatism is caused by an irregularly shaped cornea and is corrected using cylindrical lenses that compensate for the uneven focus in different meridians of the eye.
Step 2: Matching them accordingly:
(i) Myopia - [C] Concave lens
(ii) Hypermetropia - [D] Convex lens
(iii) Presbyopia - [A] Bifocal lens
(iv) Astigmatism - [B] Cylindrical lens
Therefore, the correct matching is: (i) C, (ii) D, (iii) A, (iv) B.
