Resolution thresholds for Landolt C's and vernier targets remain the same whether target is stationary or moving with horizontal vertical velocities of up to 2.5°/s foveal presentations lasting 0.1 0.2 s. Oblique motions are tolerated only 1°/s. Because visual pursuit ruled out by randomization direction motion short exposure, it concluded that a retinal image not prerequisite good acuity.
