      <subfield code="a">The measurements were made of the muscular contractions and relaxations of accommodation and of visual evoked potential (VEP) before and after one hour's visual load, checking calculations. The results showed that the relaxation time in accommodation lengthened and the latency of the positive wave appearing at about 100 ms in VEP increased with the increase in visual load</subfield>
