Occasionally a school child is reprimanded for his failure to follow directions, thought to be slow to understand, or accused of "trying to be funny" because it is not known to his teacher that he has a deficiency in color vision. Such a situation can confuse and embarrass a child, new to school and eager to please and to do well, and can also embarrass a busy and conscientious teacher who has not been apprised in advance of each of her pupils' physiological attributes. For these reasons a screening test of color vision would seem to be an appropriate part of the initial school health examination.
The importance of discovering any handicaps which a child may have before he enters school has become more widely recognized. When the initial school experience is a happy and successful one, the likelihood is enhanced that the child will develop good attitudes toward school;
