A STUDY OF INDIVIDUAL VARIABILITY IN DARK ADAPTATION AND NIGHT VISION IN MAN

A COMPREHENSIVE ANALYSIS OF THE SIGNIFICANCE OF INDIVIDUAL VARIATION IN HUMAN NIGHT VISION CAPABILITY IS REPORTED. THE ORIGIN AND MAGNITUDE OF INTER- AND INTRA-INDIVIDUAL VARIATION IN THE SEVERAL PHYSIOLOGICAL AND BEHAVIORAL PROCESSES THAT CONSTITUTE DARK ADAPTATION AND SCOTOPIC VISION ARE REVIEWED. THE GENETIC, SOMATIC, AND BEHAVIORAL FACTORS THAT EXHIBIT VARIATION AND THE ENVIRONMENTAL FACTORS AFFECTING VARIATION ARE DISCUSSED. GAPS IN THIS KNOWLEDGE THAT BEAR ON THE REQUIREMENTS FOR EFFICIENT NIGHT VISION IN THE SOLDIER ARE IDENTIFIED. IT IS SUGGESTED THAT RECOGNITION OF INDIVIDUAL VARIATION IS CRITICAL TO THE CONCEPT OF SELECTING KEY INDIVIDUALS FOR SPECIFIC DUTIES REQUIRING NIGHT VISION CAPABILITY. /AUTHOR/
