eye defects that some people assert that the eye tests at school originate with opticians more intent upon selling spectacles than upon helping children. In fact, even among educators who proclaim the need for eye tests there has been far more talk of eyeglasses than of removable conditions that cause eye strain. The women principals of New York City have sounded an alarm, and urge more attention to light and to reading position, more rest, more play, more hand work, less home study and less eye work at school, rather than more eyeglasses to conceal temporarily the effect of abusing children's eyes. Putting glasses on children without changing causal conditions is like giving alcohol to consumptives. The feeling of relief is deceptive. The trouble grows worse.

For some time to come eye tests will find eye troubles by the wholesale in every industrial and social class, in country as well as city schools. In 415 New York villages 48.7 per cent of school children had defects of vision, this without testing children under seven, while 11.3 per cent had sore eyes.

There are three possible ways of remedying defects: (1) changing the eye by operation; (2) changing the light as it enters the eye by eyeglasses; (3) decreasing the demands made upon the eye. To change eyes or light requires a technical skill which few physicians as yet possess. It will be remembered that it is but thirty years since the medical profession in America first began to understand the relation of eye defects to other defects. Until a generation of physicians has been trained by medical colleges to learn the facts about the eye and to apply scientific remedies, it is especially necessary that teachers and parents reduce the demands made upon children's eyes; oral can be substituted for written work, manual for optical work, relaxed and natural movement for discipline, outdoor exercise for less home study. Other requirements are

suitable light and proper position, and abolition of shiny paper, shiny blackboard, and fine print. Even after it is easy to obtain the correction of eye defects it will still be necessary to adapt the demands upon children's eyes to the strength and shape of those eyes. Because we are born farsighted, nearsighted, and astigmatic, we must be watchful to eradicate conditions that aggravate these troubles. Finally, there is no excuse whatever for permitting the parent of any school child in the United States to remain ignorant of the fact that it is just as absurd to go to the druggist or jeweler for eyeglasses as to the hardware store for false teeth.

The education of physician, oculist, and optician can be expedited by eye tests in school and by the follow-up work of schools in removing the prejudice of parents against glasses when needed. Because knowledge of chemistry preceded knowledge of the human body, the teaching of medicine still shows the effect of predilection for the remote, the problematical, the impossible. This predilection has influenced many specialists as well as many general practitioners, both overlooking too frequently obvious causes that even intelligent laymen can be taught to detect. Very naturally the man who makes money out of attention to simple troubles has stepped into the field not as yet occupied by the general practitioner and the specialist. Thus we have the optician, the painless tooth extractor, and quack cures for consumption. Opticians are placing before hundreds of thousands simple truths about the eye not otherwise taught as yet. Because they make their money by selling eyeglasses and because their special knowledge pertains to glasses rather than to eyes they frequently fail to recognize their limitations.

Physicians feel very strongly that it is as unethical for an optician to fit eyeglasses without a physician's prescription as for a pharmacist to give drugs without a physician's

prescription. The justification for this feeling should be based not upon the commercial motive of the optician but upon his ignorance. A physician uninformed as to eye troubles is just as unsafe as an optician determined to sell glasses. It must be made unethical and unprofessional for physician and optician alike to prescribe in the dark. Laymen and physicians must be taught that it is just as unethical and unprofessional for oculists and physicians to fail to bring their knowledge within the practical reach of the masses as for the optician to advertise his wares. School tests will not have been used to their utmost possibilities until optician and physician alike take the ethical position that the first consideration is the patient's welfare, not their own profits. It must soon be recognized as unethical and unprofessional for an optician who is also a skilled physician to refer patients to a medical practitioner ignorant as to optical science.

Whether opticians and physicians are unprofessional or unethical may be told by reexamination if the examiner is himself competent and ethical. There is no better judge of their efficiency than the patient himself, who can tell whether the results promised have been effected. Whether the work of a country oculist is efficient and ethical can be learned: (1) by teaching country school children to recognize eye strain; (2) by comparing his results with those of other physicians. As soon as one or two states have tested eyes, we shall have an average by which to compare each class, school, and city with others of their size under similar conditions. If a particular physician finds half as many more or only half the average number, the presumption will be that his results are inaccurate and warrant an investigation. The interested teacher or parent can render an inestimable service to her local school and to the children of her state by taking steps to secure state laws compelling eye tests in all schools.

Finally, it must be remembered by teachers, employers, parents, and all eye users that eyes are constantly changing; that eyes may need glasses six months after they are examined and found sound; that glasses change or develop the eye, so that they may be unnecessary and harmful six months after they are prescribed, or the eye may require a stronger glass; that eyeglasses become bent and scratched, so that they worry and strain the eye; that a periodic examination is essential to the health of the eye.

In caring for the health of the eye, we should also remember that our eyes are our chief interpreters of the world that gives us problems, profits, and pleasures. Out of gratitude, if not out of enlightened self-interest, we owe our eyes protection, attention, and training, so that without straining we shall always be able to see truth and beauty.

CHAPTER VIII

EAR TROUBLE, MALNUTRITION, DEFORMITIES

The presence of adenoids is a frequent cause of both slight and aggravated deafness. Of 156 deaf mutes examined 59 per cent had adenoids, while only 6 per cent of the general run of the children in the neighborhood had this trouble. In mouth breathing, the current of air entering the mouth draws out some of the air from the Eustachian tube which ventilates the middle ear and unequalizes the atmospheric pressure on the eardrum, causing it to sink in and to blunt the hearing. An examination of the eardrums of school children in New York who are mouth breathers showed a high percentage of deafness, incipient or pronounced, accompanying adenoids. For example, of 9 mouth breathers selected from one class (average age 7-8 years), 6 were well-marked cases of deafness. Of 8 mouth breathers (average age 8-9 years), and of 5 mouth breathers (average age 5-6 years), all had noticeable defects of hearing. Many adults that suffer from deafness maintain that they never had any trouble in childhood. Yet the evidences of nose and throat trouble in childhood persist and disprove such statements. The foundations of deafness in later life are, in most instances, laid in childhood. Since the majority of cases of ear trouble occurring in school children accompany diseased conditions of the nose and throat, the proper care of nose and throat will, in large measure, balance the shortcomings of the aural examinations. Since the examination of the drum itself is not practicable, especial care should be given to the examination of the nose and throat.
