(a) Redraw your ray optics diagram for the eye, but now position the screen (retina) too far from the lens for parallel rays from a distant object to converge, labeling s, s', and f.

(b) Discuss two ways this myopia (nearsightedness) could be corrected.

(c) Now redraw your ray optics diagram for the same eye too large, but now place a point object closer to the eye (so its rays diverge from the point) and such that it is now able to be focused onto the retina. Label the distances s, s', and f. If f is the same as in the first diagram above (i.e. eye muscles relaxed as much as possible to give the longest f), what will happen to s'? (Note that this person can view near sights clearly, but distant objects are out of focus.)

The previous question was: Wh
