constant lookout for these symptoms of good sight persisting in spite of imperfect eyes. An epidemic of eyeglasses is usually the consequence of eye tests. So naturally do we associate eyeglasses with 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.
