Q. For a person having hypermetropia, the near point is__:
Answer: greater than 25 cm
Notes: For a hyper-metropic eye ,the near points shift away from the eye i. e. farther away from the normal near point (25cm). In a hypermetropic eye, the light is not bent sufficiently so that it focuses at a point behind the retina. Here a person sees well for distance but near vision is difficult and causes strain. Hence, hypermetropic people are called long-sighted. To correct the hypermetropic eye, a plus lens (convex lens) is used to focus image on retina.
