Monocular and binocular accommodation amplitude evaluating assembly for near vision, has mobile target sliding on rod to provide accommodation value for determining addition value, in abacus, to be added to ametropia compensation value
摘要
<p>The assembly has a subjective evaluation device with a mobile target (1) having back-lighted stenopaic apertures to control ocular partition power. The target slides on a support rod (2) having graduations such that position of the target on the rod provides a value of accommodation set by a patient for determining a prescribable addition value, in an abacus, to be added on a value of ametropia compensation in presbyope distant vision.</p>
