Answer: Column 1Column 2Column 3 FarsightednessFaraway object can be seen clearlyConvex lens PresbyopiaProblem of old ageBifocal lens NearsightednessNearby object can be seen clearlyConcave lens Explanation: Farsightedness (hypermetropia): A person sees distant objects clearly but not nearby ones. The image of a near object forms behind the retina because the eyeball is shorter or the focal length of the eye lens is too long. A convex (converging) lens brings the image onto the retina. Presbyopia: With age, the ciliary muscles weaken and the eye lens loses flexibility, so nearby objects are not seen clearly; often distant vision is also affected. A bifocal lens is used: the upper part (usually concave) for far vision and the lower part (convex) for near vision. Nearsightedness (myopia): A person sees nearby objects clearly but not distant ones. The image of a distant object forms in front of the retina because the eyeball is longer or the lens is too curved. A concave (diverging) lens corrects it.
