Question

The condition of hyperopia (far-sightedness) can arise when the distance between your eye's lens and retina is smaller than appropriate for the range of focal lengths of your eye lens. Suppose that the distance between your lens and retina is actually 1.62 cm but the minimum and maximum focal lengths of your lens are the same as in problem 1. 4. Using the appropriate focal length, what is the near point of your vision in this condition? How does this compare to the near point of normal vision, 25 cm? a b. When you hold this page 25 cm in front of your eye, it appears blurry. Where is the image of the page created by your eye lens located? is it in front of or behind your retina? c What sort of corrective lens do you need to see the page clearly when it's 25 cm in front of your eye? Explain how you can d. Suppose you place the necessary corrective lens directly in front of the lens of your eye (we will ignore orrective lens form an any distance between the eye's lens and the corrective lens). Where should the c image of the page when t's 25 cm in front of your eye, and what kind of image is it? e. Determine the focal length of the corrective lens needed to see the page clearly when it's 25 cm in front of your eye. is the sign of your answer consistent with part c?
