title: Speed of visual acuity for vertical eye-movements with a change of accommodation.
abstract: Speed of visual acuity was measured for Landolt-C targets presented above and below the line of sight as the targets were moved from 2.4 m to 0.6 m from the observer. Target recognition was faster for a downward than an upward eye movement. There was no difference in response times for the up and down eye-movements when the fixation and target distances were the same.
