Eye-head coordination with laterally "modulated" gaze field.
Discrimination of peripheral targets is possible with progressive lenses if visual strategy is changed. However, there is a penalty in response time. This penalty is reduced after adaptation. This adaptation involves making earlier and more rapid head movements on the one hand, and recalibrating the saccadic and vestibulo-ocular systems on the other hand. These changes enable subjects to gaze directly through a zone of the lenses where discrimination is possible. This adaptation also consists of learning to use information from blurred images. In this way visual processing can begin earlier.
