摘要
<p>The method involves determining visual acuity of human eyes using an electronic data processor. The electronic data processor performs electronic and optical data retransmission using defined image resolution on a fluorescent screen to measure eyesight or vision and for assigning corrective lens for the examined eyes. The eyes to be examined are placed at a 20 to 200 cm distance with respect to the fluorescent screen.</p>
