Expert Says Good Vision Vital to Child Welfare Educators in the United States are paying increasing attention to the visual equipment of children, for studies have demonstrated repeated-1 repeated-1 ly that visual defects not only retard re-tard the acquisition of knowledge,' but they may breed undesirable social so-cial qualities, according to M. J. Julian, president of the Better Vision Vi-sion institute. "Extensive studies have shown that two important factors are involved in-volved in defective vision: (1) the physical and (2) the mental. A child who cannot see well cannot read and carry on his tasks easily at school. Correcting such defects naturally facilitates education of children. However," says Mr. Julian, "the eyes have an important effect upon the nervous system and the mental states of the child. Headaches Head-aches and nervous irritability are caused by defective eyes. Frequently Frequent-ly undesirable social habits, including includ-ing juvenile delinquency, can be traced to uncorrected visual defects. Poor eyes definitely tend to make "difficult children" out of some youngsters. Several authorities go so far as to say that failure to correct cor-rect visual defects in children is an important factor in truancy. One calls attention to the fact that a substantial sub-stantial part of the inmates of reform re-form schools have defective vision.
