Oculist and opticians treat all defects of vision by glasses, which are given to rectify and normalize eyesight. If a patient is long sighted and can read a book only at a distance of 3 feet he will be given glasses which enable him to read at the normal distance of 12 inches; if he is short sighted and can read only at a distance of 2 or 3 inches he is given glasses enabling him to read at a normal distance. Similar methods are used for astigmatism, and they are satisfactory as far as they go.
People who could read only with difficulty rejoice when glasses enable them to read with ease, but the comfort thus obtained is occasionally dearly bought. The eye is comparable to the telescope. In the telescope two factors are of importance, the lenses and the apparatus of adjustment whereby the distance between the lenses is increased or diminished at will. A telescope with the best lenses is almost useless if the apparatus of adjustment has broken down, for then it can be used only at a fixed distance and no other.
The eye has a wonderful apparatus of adjustment provided by a set of muscles, the non-use of which leads to defects of vision. Defects of vision due to the muscles controlling the apparatus of adjustment should obviously be cured not with glasses but by strengthening the muscles with adequate exercise, massage, splashing with hot or cold water, or whatever may be needed according to the nature of the case. Captain Price has written a valuable book on the natural methods of improving eyesight. These methods were invented by an American oculist, Dr. Bates, who has found numerous disciples throughout the world.
Captain Prices book is of distinct value. It is plainly and popularly written and it will undoubtedly appeal to wide circles. Even oculists and opticians who dislike the competition of those who succeed in improving eyesight without glasses have acknowledged the value of this book. The well-known journal, The Optician, wrote in a review:.
“Opticians curious to learn the principles upon which the so- called natural methods of eyesight training are based have hitherto found difficulty in satisfying their curiosity. The book under review removes that difficulty. Little fault can be found in the way in which the author presents his technique. The book is refreshingly free from the sweeping condemnation of orthodox methods which characterizes most of the literature emanating from the unorthodox school. There is a good deal in the book with which no fault can be found even by the most ardent devotees of the orthodox school. The authors chapter on squint treatment will especially interest such readers”.
The book is distinctly recommendable and it should have a large sale among oculists, opticians and, last, but not least, among the general public.
