This question requires matching common eye diseases/conditions with their standard remedies. Hypermetropia (farsightedness) is corrected with convex lenses. Presbyopia (age-related difficulty with near vision) is often managed with bifocal or progressive lenses. Myopia (nearsightedness) is corrected with concave lenses. Cataracts, which involve clouding of the eye’s lens, are primarily treated by surgical removal of the clouded lens and replacement with an artificial one. Thus, the correct matches are A-4, B-2, C-1, D-3.
Different refractive errors require specific types of corrective lenses based on how they affect the focusing of light on the retina. Cataracts are a structural issue requiring surgical intervention.
