Some one – perhaps it was Bacon – has said: “You cannot by reasoning correct a man of ill opinion which by reasoning he never acquired.” He might have gone a step further and stated that neither by reasoning, nor … more...

The following letters have been selected almost at random from the author’s mail-bag, and are only specimens of many more that are equally interesting. They are published: because it was s felt that the personal stories of patients, told in … more...

The Great War is over, and among the millions of brave men who- laid down their lives in the cruel conflict there were some who thought that they were doing so that wars might be no more. But the earth … more...

Poor sight is admitted to be one of the most fruitful causes of retardation in the schools. It is estimated(1) that it may reasonably be held responsible for a quarter of the habitually “left-backs,” and it is commonly assumed … more...

The efficacy of the method of treating imperfect sight without glasses presented in this book has been demonstrated in thousands of cases, not only in my own practice but in that of many persons of whom I may not even … more...

You cannot see anything with perfect sight unless you have seen it before. When the eye looks at an unfamiliar object it always strains more or less to see that object, and an error of refraction is always produced. When … more...

No phase of ophthalmology, not even the problem of accommodation, has been the subject of so much investigation and discussion as the cause and prevention of myopia. Since hypermetropia was supposed to be due to a congenital deformation of the … more...

Correspondence treatment is usually regarded as quackery, and it would be manifestly impossible to treat many diseases in this way. Pneumonia and typhoid, for instance, could not possibly be treated by correspondence, even if the physician had a sure cure … more...

It is not always possible for patients to go to a competent physician for relief. As the method of treating eye defects presented in this book is new, it may be impossible to find a physician in the neighborhood who … more...

A very common phenomenon of imperfect sight is the one known to medical science as muscae volitantes or flying flies. These floating specks are usually dark or black, but sometimes appear like white bubbles, and in rare cases may assume … more...

The evidence is conclusive that squint and amblyopia, like errors of refraction, are purely functional troubles; and since they are always relieved by the relief of the strain with which they are associated, it follows that any of the methods … more...

NOTE: The modern term for squint is strabismus. He isn’t referring to narrowing the eyes.

Since we have two eyes, it is obvious that in the act of sight two pictures must be formed; and in order that these two-pictures … more...

Among people living under civilized conditions the accommodative power of the eye gradually declines, in most cases, until at the age of sixty or seventy it appears to have been entirely lost, the subject being absolutely dependent upon his glasses … more...

Many years ago patients who had been cured of imperfect sight by treatment without glasses quite often told me that after their vision had become perfect they were always relieved of pain, not only in the eyes and head, but … more...

In nearly all cases of imperfect sight due to errors of refraction there is some object, or objects, which can be regarded with normal vision. Such objects I have called “optimums.” On the other hand, there are some objects which … more...

According to accepted ideas of ocular hygiene, it is important to protect the eyes from a great variety of influences which are often very difficult to avoid, and to which most people resign themselves with the uneasy sense that they … more...

Persons with imperfect sight always have illusions of vision; so do persons with normal sight. But while the illusions of normal sight are an evidence of relaxation, the illusions of imperfect sight are an evidence of strain. Some persons with … more...

When the eye with normal vision regards a letter either at the nearpoint or at the distance, the letter may appear to pulsate, or to move in various directions, from side to side, up and down, or obliquely. When it … more...

We see very largely with the mind, and only partly with the eyes. The phenomena of vision depend upon the mind’s interpretation of the impression upon the retina. What we see is not that impression, but our own interpretation of … more...

When the mind is able to remember perfectly any phenomenon of the senses, it is always perfectly relaxed. The sight is normal, if the eyes are open; and when they are closed and covered so as to exclude all the … more...
