Many practitioners have thousands of cards in their patient files which might be used to determine the visual conditions of clinical patients when they appear for examination. From the standpoint of the motor vehicle administrator, two other problems exist. One treats of what the practitioner would find if he were to examine a random sampling of the population to ascertain the extent of visual defects, using regular clinical methods. The other deals with the percentage of defects which a trained examiner giving regular driver’s license examinations might find in a non-clinical population. By non-clinical we mean a sampling of the population which would voluntarily submit for an examination on general psychophysical traits without exclusive consideration of the eye as a sense organ. It is felt that the data secured by such a study may be of value in helping the practitioner decide the merits of any specific case which may be brought up for consideration in states where mandatory regulations must be interpreted by expert testimony in order to settle questions of legality.
