o dioptrics of refraction, we may readdirectly from its graduations, the amplitudes of accommodation in emme-tropia, provided the distance is measured from the cornea to the test-object,on the median line. The same procedure will apply in any case ofametropia, when the distance glasses which… … 190 THE COEEECTION OF DEPLETED DYNAMIC REFEACTION. comparatively easy to determine the proper distance glasses, as well as forthem to predict, with reasonable certainty, that the lenses will be worn,with comfort. But when the case is complicated with a loss of dynamicrefraction, and unless extreme…
