Taking values for refractive indices and separation of elements from the schematic of the unaccommodated eye given in Table 19-2 and Figure 19-3, determine the distance behind the cornea where an image is focused for (a) an object at infinity and (b) an object at 25 cm from the eye. Use the Gaussian formula for image formation by a spherical surface in a three-step chain of calculations. In part (b), assume that the fully accommodated eye differs in the following ways: The front surface of the lens is more sharply curved, having a radius of +6 mm, but the back surface remains at −6 mm. As a result, the thickness of the lens along the axis increases to 4.0 mm, and the distance from cornea to the front surface of lens is shortened to 3.2 mm.
