Match List I with List II and select the correct answer using the code given below the Lists : List I List II (Disease) (Remedy) A. Hypermetropia 1. Concave lens B. Presbyopia 2. Bifocal lens C. Myopia 3. Surgery D. Cataract 4. Convex lens Code : A B C D

The correct matching of eye diseases to their remedies is as follows: Hypermetropia (farsightedness) is corrected using a convex lens, which converges light rays to focus them properly on the retina [1]. Presbyopia, an age-related loss of lens flexibility, is typically managed with bifocal lenses that contain both concave and convex sections to assist with both distance and near vision [3]. Myopia (nearsightedness) occurs when images focus in front of the retina; it is corrected using a concave lens, which diverges light rays to move the focal point back onto the retina [3]. Cataract involves the clouding of the eye's natural lens, and the primary medical remedy is surgery to replace the opaque lens with an artificial intraocular lens [3]. Therefore, the correct sequence is A-4, B-2, C-1, D-3.
