Third edition.

In this book, author W. G. Bates, who is widely known for his discovery of several properties of the adrenal hormone (known as "adrenaline"), as well as his ophthalmological research, presents evidence that most of the accepted theories about the eye are wrong. The book describes the following points:

SUMMARY of animal experiments and clinical observations that demonstrate that the lens is not a factor in accommodation and that all refractive errors (nearsightedness, farsightedness, astigmatism and even senile vision) are functional and curable diseases|

THE TREATMENTS that have achieved cures in thousands of clinical cases|

THE USE OF THESE METHODS, people are often able to heal themselves.

Full scientific, this book is nevertheless written in such a language that any intelligent person who is not a specialist in ophthalmology can understand.
