) In myopia the image moves in a sense contrary to that of the observer's head, and the more so the farther it is in front of the ob- served eye. In hypermetropia it moves with the head of the observer, and the excursion is less. (3. ) The observer, as a rule, can tell whether he is accommodating for an image which lies in front of the eye examined, or behind it, the difference in the position of the images even in high degrees of the two kinds of ametropia being considerable. Suppose, in this ...connection, the observer is emmetropic, and that his near point lies in six inches. He can then accommodate for an object at that distance, but no nearer. In a given case in putting up the mirror he gets an image which, on his gradually approaching his head and exerting in a corresponding degree an increased tension on his accommodation, remains distinct up to a certain point, when sud- denly it begins to grow a little indistinct. Withdrawing his head a trifle till the image is clearly defined again, the observer know r s that the image must lie six inches in front of his own eye.
