A patient's far point is 135 cm and her near point is 15.0 cm. In what follows, we assume that we can model the eye as a simple camera, with a single thin lens forming a real image upon the retina. We also assume that the patient's eyes are identical, with each retina lying 1.95 cm from the eye's "thin lens." (a) What is the power, P, of the eye when focused upon the far point? (Enter your answer in...

All eyeglass lenses have chromatic aberration. This is usually expressed as dioptric spread. For a typical +6.0 D lens, the focusing power for red light is +5.90 D, the power for green light is +6.00 D, and the power for blue light is +6.10 D. This gives a dioptric spread of 0.20 diopter. Suppose a myopic person is observing a distant object through this lens, and the green light of the image is in perfect focus. Assume a distance s′...
