Photographing eye movements to obtain both high resolution and large amplitude applied to the experiment of J. Mueller.
A method is described by which very small eye movements may be photographed over a wide angle, using the optical-lever technique. The method is applied to photographing eye movements for the experiment of J. Mueller. The fixating eye makes "irrelevant" movements that are not observable under direct observation or with less sensitive recording methods. The eye-movement records were measured, and the velocity and acceleration of accommodative vergence were determined for two amplitudes.
