Figure 4.
Examples of raw data collected from an adult and an infant in the CL and VOL conditions. The infant’s accommodation data in the VOL, monocular, condition demonstrate that the accommodation is consensual at this age. The accommodation and vergence data are plotted relative to infinity, although the instrument was not calibrated for individual subjects (in terms of dioptric calibration, angle lambda or the Hirschberg ratio). The temporal structure of the response is therefore accurate, but the dioptric or angular response accuracy was not tested.
