A. You are looking at an object 1.75 m tall 30 m away from you.
Assuming the eye is completely relaxed and that the nodal point of
the eye is 1.65 cm in front of the retina, calculate the height of
the image of the object on the retina, assuming that it is in
focus. What is the focal length and the refractive power of the eye
under these conditions?
B. You have shifted your focus to a nearby object 12 cm tall
located a mere 0.6 m away. In doing so, your eye accommodates to
bring its image into focus on the retina. What is the refractive
power of the eye in this case? How tall is the image on the
retina.
