New light on the eyes - Revolutionary and scientific discoveries which indicate extensive reform and reduction in the prescription of glasses and radical improvement in the treatment of diseases such as cataract and glaucoma #549127

Today, millions of men, women, and children, throughout the World, depend upon glasses. To the very many who ask, as did the Author thirty years ago, when he too was very shortsighted, `need such things be?' this book is of outstanding interest. Written in simple words for the laity, who are entitled to an understanding of their eyes, this book is also of profound importance to the ophthalmic and optical professions. It solves many of the problems of why eyes, normal at birth, develop refractive errors. It also introduces methods for the prevention of Cataract and Glaucoma, as well as rational treatment of these diseases. The universal prescription of glasses to-day is based upon an 'hundred years old' theory that astigmatism is congenital, that shortsighted eyes are permanently too long, and longsighted eyes too flat, and that all adjustments of focus for near vision depend solely upon the small natural lens inside the eye incessantly changing its curvature and strength. In contradiction, however, the Author has proved, and depicts, with the aid of simple diagrams, that astigmatism is caused by irregular muscular tension on the pliable eyeball, and that normal eyes involuntarily lengthen to produce 'natural shortsight' for near vision, automatically return to an 'at rest' condition for distance vision, and arc mechanically capable of flattening for extreme distance vision or very longsight.
