Differences among myopes, emmetropes, and hyperopes.
One hundred fifty-two military recruits were classified as myopes, emmetropes, or hyperopes based on their measured farpoint. Height, weight, education, personality scores from the three scales of the Eysenck Personality Inventory, heart rate variability, autonomic nervous system indices, nearpoint, and dark focus were recorded for each subject. These were compared among groups using one-way analyses of variance and four discriminant analyses. Reliable differences were found among groups in each area referred to above: myopes weight less, completed more grades, had higher heart rate variability, and nearer nearpoints than hyperopes. Furthermore, myopes wee more consistent in their responses on the Eysenck Personality Inventory than emmetropes.
