A 72 year old woman has a near point of 88 cm. What power lens (in diopters) does the woman need in order to be able to see an object clearly at the normal near point of 25 cm? Assumethat the woman will get contact lenses, that is neglect the two centimeters that glasses would be away from the eye.3805This is an example of farsightedness. The correcting lens (converging in this case) has to move the (virtual) Image of an object placed at the normal near point (o) to the actual near point dthe worhan (1). Then you can calculate the focal length of the lens. Remember that the image is virtual.Sub A Incorrect. Tries 1/99 Previous TriesPost DiscussionSend Feedb
