What is the distance to the focus (within the eye) of a small object (e. g. a point source of light) that is on the axis of sight, 10 cm from the front of the cornea, for this eye model? Assume that the distance to focus of the light rays from this point source that enter the eye at y = 1 mm yields a good approximation of the overall distance to the focus. Next, assume that the radius of curvature of the cornea, RC, could change (much like that of the lens in an actual eye) to refocus the light on the back of the eye (i. e. use the value of fl found in part b as y  0 for the distance to the retina). What would the new radius of curvature need to be to accommodate our vision to focus on this nearby object? You may again use y = 1 mm for your math. Also assume that changing RC via accommodation does not change the distance to the back of the retina,
