There is little information on the accommodative response to stimuli having naturalistic motion on the retina. In the present experiment, the steady‐state accommodative response al various dioptric levels was assessed with a Hartinger coincidence optometer as sinusoidal frequency of a small target was systematically altered across the horizontal foveal region (±2°). The steady‐state accommodative response became less accurate as target oscillation frequency increased, approaching the tonic accommodation level when the frequency was between 0.5 and 1 Hz (corresponding to peak velocities of 6.3 and 12.6 deg s−1, respectively). These results suggest that the accommodation system is reasonably robust to naturally‐occurring retinal‐image motion.
