CHAPTER I: Who Is Responsible? [1]
This section recommends that you be prepared to enter into an aggressive analytical effort if you wish to come to grips with the problem of nearsightedness. The approach must include the development of a clear understanding of the strengths and weaknesses of current eye care practices.

CHAPTER II: Practical Nearsightedness Avoidance [7]
This chapter provides a discussion of a systematic effort that you can institute to avoid myopia.

CHAPTER III: The Effect of a Negative Lens on the Normal Eye [19]
The effect that a negative lens has on the natural eye is established by scientific judgments and experiments developed over the last eighty years. The basic physics of refraction are discussed as they concern the eye.

CHAPTER IV: A Nearsightedness Computer [33]
This analysis presents an electronic computer used to portray the eye's behavior. This scientific approach reviews the data that establishes of the eye's performance when experimentally tested.

CHAPTER V: Physiological Modeling: The Long-Term Growth of the Eye [43]
Further review is provided in the form of a thought-experiment designed to simplify and clarify your understanding of eye's behavior.

CHAPTER VI: The Response of a Dynamic Eye to a Confined Visual Environment [51]
In so far as the experimental data can actually demonstrate the basic operating characteristic of the normal eye, this chapter supplies that verification.

CHAPTER VII: A Predictive Mathematical Model for the Eye's Focal Status [65]
A quantitative understanding of the eye requires the development of a basic equation for the normal eye's behavior. The equation developed in this chapter can be solved on a personal computer, and will accurately predict the results of all possible tests that can be conducted to establish the normal eye's behavior.

CHAPTER VIII: A Conceptual Model for Tonic Accommodation [81]
This chapter reviews "dark-focus" of the eye. The normal eye, in darkness, has a slight negative focal state. (This focal state is also called blank-field accommodation.)

CHAPTER IX: The Response of a Dynamic Eye to Focal Perturbations [91]
The normal eye must continue to adjust and readjust its long-term focus. If the normal eye did not have this dynamic control characteristic (which has been experimentally demonstrated) it would be impossible to account for the fact that all eyes have a focal status that is almost identical to their visual environment, offset by +1.5 diopters.

CHAPTER X: Measuring the Eye's Focal Accuracy: A Conceptual Approach [101]
The normal eye is highly accurate (in a dynamic sense) relative to its average environment. This chapter establishes a numerical value for the tracking accuracy of the system.

CHAPTER XI: But Does it Work? [113]
A number of students and pilots, who have worked with the plus lens, detail their experience and judgment about the long-term use of the lens. Currently practiced methods, and objections to those methods are documented by eye doctors who have extensive experience with the negative lens. Books and services to assist you in returning your vision to 20/20 are also recommended.
