Chapter 25, Problem 43GP

Physician, heal thyself! (a) Experimentally determine the near and far points for both of your own eyes. Are these points the same for both eyes? (All you need is a tape measure or ruler and a cooperative friend.) (b) Design correcting lenses, as needed, for your close-up and distant vision in one of your eyes. If you prefer contact lenses, design that type of lens. Otherwise design lenses for ordinary glasses, assuming that they will be 2.0 cm from your eye. Specify the power (in diopters) of each correcting lens.
